PCAL6524HE Integrated Circuit Chip Ultra-Low-Voltage Translating 24-Bit Fm+ I²C-Bus/SMBus I/O Expander

PCAL6524HE Integrated Circuit Chip Ultra-Low-Voltage Translating 24-Bit Fm+ I²C-Bus/SMBus I/O Expander

Product Description Of PCAL6524HE
PCAL6524HE is a 24-bit general purpose I/O expander that provides remote I/O expansion for many microcontroller families via the Fast-mode Plus (Fm+) I²C-bus interface. The ultra-low-voltage interface allows for direct connection to a microcontroller operating down to 0.8 V.

Specifications Of PCAL6524HE

Features Of PCAL6524HE
I²C-bus to parallel port expander
1 MHz Fast-mode Plus I²C-bus
Operating power supply voltage range of 0.8 V to 3.6 V on the I²C-bus side
Allows bidirectional voltage-level translation and GPIO expansion between 0.8 V to 3.6 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V, 5.5 V Port P
Low standby current consumption: 2.0 µA typical at 3.3 V VDD(P)
Schmitt trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs
Vhys = 0.05 V (typical) at 0.8 V
Vhys = 0.18 V (typical) at 1.8 V
Vhys = 0.33 V (typical) at 3.3 V
5.5 V tolerant I/O ports and 3.6 V tolerant I²C-bus pins
Active LOW reset input (RESET)
Open-drain active LOW interrupt output (INT)
Internal power-on reset
Noise filter on SCL/SDA inputs
Latched outputs with 25 mA drive maximum capability for directly driving LEDs
Latch-up performance exceeds 100 mA per JESD 78, Class II
Output port configuration: bank selectable or pin selectable push-pull or open-drain output stages
Interrupt status: read-only register identifies the source of an interrupt
Interrupt edge specification on a bit-by-bit basis
Interrupt individual clear without disturbing other events
Read all interrupt events without clear
Switch debounces hardware
General call software reset
I²C software Device ID function
ESD Protection Exceeds JESD 22
2000 V Human-Body Model (A114-A)
1000 V Charged-Device Model (C101)
Bit-Wise I/O Programming Features
Output drive strength: four programmable drive strengths to reduce rise and fall times in low-capacitance applications
Input latch: Input Port register values changes are kept until the Input Port register is read
Pull-up/pull-down enable: floating input or pull-up/pull-down resistor enable
Pull-up/pull-down selection: 100 kΩ pull-up/pull-down resistor selection
Interrupt mask: mask prevents the generation of the interrupt when input changes state to prevent spurious interrupts
