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

Description

Part Number:	PCAL6524HE	Interface Type::	I2C, Serial, SMBus
Number Of I/Os::	24 I/O	Supply Voltage - Min::	800 MV
Supply Voltage - Max::	3.6 V	Maximum Clock Frequency::	1 MHz

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

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

Number of I/O	24
Interface	I2C
Interrupt Output	Yes
Features	POR
Output Type	Open Drain, Push-Pull
Clock Frequency	1 MHz
Voltage - Supply	1.65V ~ 5.5V
Operating Temperature	-40°C ~ 85°C

Key Features

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
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 standards
Bit-Wise I/O Programming Features including output drive strength, input latch, pull-up/pull-down enable, pull-up/pull-down selection, and interrupt mask
