I2 C Storage SSD The I2C-bus assumes the possibility of simultaneous bi-directional signal flows. – Without any buffers, the bus wires are clearly bi-directional. Conventional buffers only handle signals traveling in one direction at any one time. – There are logic buffers with a direction control pin, but at any one time they are uni-directional. I2C-bus Buffers for use on an must not have any pull-up capability. They must have open-collector or open drain outputs. If two conventional logic buffers are connected as shown then they will simply latch to the LOW state the first time either side goes LOW. – The logic symbol represents a noninverting, open drain, buffer. If side A is externally pulled LOW, then the upper open drain buffer pulls the bus at side B to the LOW level. With this LOW now on side B, the lower buffer will pull side A LOW and even if the external drive at A is removed the buses at A and B will simply remain latched LOW. A special type of buffer is required for I2C-bus. 69 Types of No Offset Characteristics: I2C-Bus I2 C Buffers Static Offset Characteristics: Incremental Offset Characteristics: • Buffer automatically changes • A fixed third logic level is • A dynamic third logic level is direction in response to the introduced on the special I/O introduced by adding an applied drive signal side incremental offset voltage • For use on SDA line ONLY • The third logic level is higher to the input • Buffer output has “no offset” (static offset) than 0.4V, but • Either bus will be driven and pulls its output down low enough to still be a low (down), by a voltage very close to 0V to the other devices on the follower, to a level 100mV bus higher than the voltage level of the other bus Storage SSD Amplifier Characteristics: • The bus current is amplified, but in only one signal direction • Current gain enables a 3-mA driver on the input side to drive a bus with 30-mA pullup on the other side 70 Pros & Cons of Different Types of Buffers + NO OFFSET • Both I/Os pull-down to zero volts for full level swing and best • Noise margin on output side • Both inputs interface with any slave and with most buffers I2 C Storage SSD _ • Only used on SDA due to glitch during auto reversing • Only class that doesn’t support clock stretch or multi-master because SCL buffer is unidirectional • User required to design Master’s timing to accommodate buffer and any system delays INCREMENTAL OFFSET • • • • • Offsets add up as parts are placed in series Good VOL as long as VIL is low enough Can be used in series or parallel Supports logic level shifting Only type where both I/Os can be fully I2C compliant HYBRID INCREMENTAL OFFSET • Good VOL as long as VIL is low enough • Variety of parts available including parts with special features such as rising edge accelerators, precharge, and current source pull-up • Offsets add up as parts are placed in series • Can only be used for level shifting when part uses dual power supplies • VIL requirement restricts the bus low voltage STATIC OFFSET • Strong drive down to VOL (~0.6 V) • Forces a restrictive low bus voltage requirement on the static offset • Wide range of single and hub parts with special features and options side offset voltage, drive strength, over-voltage tolerance, offset on only one • Side using offset generally cannot interface with other buffers side or all sides • Work with any slave when bus low voltage is acceptable AMPLIFIER • Allows driving high capacitance (~4000 pF) with low value pull-up resistors • Strong drive (30mA) • No input level switch points • No enable • Not over-voltage tolerant • Input not isolated from output 71 Hot-Swappable Buffer Value Proposition I2 C Storage SSD 92-mA Current Source ESD (HBM) Why used? – During hot-swapping, glitches on the SCL and SDA lines may cause data corruption on the I2C-bus.

Solves concern with PCA9541A that both masters could select the slave around the same time, and the last one to perform the write would be the one that gets control of the bus without the other master knowing it didn’t have control. Neither channel 0 or 1 selected at start up and is deselected after stop condition. Master 0 and Master 1 arbitration. Arbitration will be performed with a fixed priority to Master 0. When a Master is done with the transmission, the PCA9641 will return to neutral Once a Master has taken control of the bus, the other master is locked out until the PCA9641 is returned to neutral. A bus time-out function will release the masters from the bus, generate a stub bus recovery sequence (9 SCL clocks to slaves), and return the PCA9641 to idle. Software reset will return the PCA9641 to start-up condition. This can also be used to kick-off another master from the slave bus if needed. BUSINIT function will generate 9 clocks downstream before connecting bus. 117 PCA9646 Fm+ 4 channel I2C Switch I2 C 1 MHz I2C-bus 30 mA Storage SSD 540 pF N O B OFF I2C Bus OFF 540 pF Reset I2C Bus 0 I2C Controller N O B I2C Bus 3 30 mA Fm+ Slave Fm+ Master 30mA 540 pF • Fast-mode Plus (Fm+) rated PCA9546A (1 MHz I2C core and 30 mA SDA drive) that works in the Fm+ system to allow Fm+ masters to fan out to four Fm+ bus segments. • Maximum speed and capacitance loading (1 MHz with 550 pF) is available on each channel due to no offset buffer integrated for each of the bus segments. • No Offset bus buffers require no masters or clock stretching on the downstream bus segments and voltage level translation is not available. 118 I2 C Storage SSD External SSD Internal SSD Temperature Sensors 119 Temp Sensor in SSD Applications High Density Memory Array (Flash) I2 C Storage SSD External SSD Internal SSD Power-hungry Controller High current Switched-mode Power Supply Temp Sensor for thermal management 120 120 I2C Temperature Sensors I2 C Storage SSD External SSD Internal SSD Determine temperature and set window for interrupt, shutdown, etc. wire local local remote diode sensor Applications – Server, workstation and storage motherboards, enterprise SSD and hybrid drives power supplies, DIMM modules Large selection of commonly used local and local/remote thermal sensors – Wide range of packages – Continuous innovation with lower voltage, smaller – package and higher accuracy 121 I2C Temperature Sensor Portfolio I2 C Storage SSD External SSD Internal SSD V RANGE 2.8 to 5.5V ACCURACY (LOCAL) ACCURACY (REMOTE) ±2 ˚C SMBus TIMEOUT YES TEMP RES. 0.125 ADC RES. 11-bit SUPPLY CURRENT operating: 300 µA standby: 1 µA NOTES industry standard, PACKAGE SO8, SSOP8, XSON8U, HWSON8 PART# LM75B (metal pad) YES 0.125 11-bit 1.7 to 3.6V YES 0.125 11-bit operating: 400 µA standby: 5 µA low voltage HWSON8 SE98A 3.0 to 3.6V YES 0.125 11-bit operating: 400 µA standby: 3 µA DDR3, 2K EEPROM HWSON8 SE97B YES 0.0625 12-bit operating: 30µA standby: 1 µA TMP102 replacement, 1.8V WLCSP6 PCT2202 2.7 to 5.5V ±1 ˚C NEW SO8, MSOP8, HWSON8, SOT23-6 (TSOP6) operating: 200 µA standby: 1 µA PCT2075 1.65 to 1.95V ±1.0˚C typ.
