40-bit Fm+ I2C-bus advanced I/O port with RESET, OE and INT
I 2.3 V to 5.5 V operation with 5.5 V tolerant I/Os
I 40 configurable I/O pins that default to inputs at power-up
I Outputs:
N Programmable totem-pole (10 mA source, 25 mA sink) or open-drain (25 mA sink)
with controlled edge rate output structure. Default to totem-pole on power-up.
N Active LOW Output Enable (OE) input pin 3-states all outputs. Polarity can be
programmed to active HIGH through the I2C-bus. Defaults to OE on power-up.
N Output state change programmable on the Acknowledge or the STOP Command to
update outputs byte-by-byte or all at the same time respectively. Defaults to
Acknowledge on power-up.
I Inputs:
N Open-drain active LOW Interrupt (INT) output pin allows monitoring of logic level
change of pins programmed as inputs
N Programmable Interrupt Mask Control for input pins that do not require an interrupt
when their states change
N Polarity Inverter register allows inversion of the polarity of the I/O pins when read
I Active LOW SMBus Alert (SMBALERT) output pin allows to initiate SMBus ‘Alert
Response Address’ sequence. Own slave address sent when sequence initiated.
I Active LOW Reset (RESET) input pin resets device to power-up default state
I GPIO All Call address allows programming of more than one device at the same time
with the same parameters
I 64 programmable slave addresses using 3 address pins
I Readable Device ID (manufacturer, device type and revision)
I Designed for live insertion in PICMG applications
N Minimize line disturbance (IOFF and power-up 3-state)
N Signal transient rejection (50 ns noise filter and robust I2C-bus state machine)
I Low standby current
I −40 °C to +85 °C operation
I ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per
JESD22-A115, and 1000 V CDM per JESD22-C101
I Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
I Packages offered: TSSOP56, and HVQFN56
I Servers
I RAID systems
I Industrial control
I Medical equipment
I Cell phones
I Gaming machines
I Instrumentation and test measurement
