PCAL6416AHF Descrizione generale
The PCAL6416A is a 16-bit general-purpose I/O expander that provides remote I/O expansion for most microcontroller families via the I2C-bus interface.
Caratteristiche principali
• 2C-bus to parallel port expander
• Operating power supply voltage range of 1.65 V to 5.5 V
• Allows bidirectional voltage-level translation and GPIO expansion between:
– 1.8 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P
– 2.5 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P
– 3.3 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P
– 5 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P
• Low standby current consumption:
– 1.5 μA typical at 5 V VDD
– 1.0 μA typical at 3.3 V VDD
• Schmitt trigger action allows slow input transition and better switching noise immunity
at the SCL and SDA inputs
– Vhys = 0.18 V (typical) at 1.8 V
– Vhys = 0.25 V (typical) at 2.5 V
– Vhys = 0.33 V (typical) at 3.3 V
– Vhys = 0.5 V (typical) at 5 V
• 5 V tolerant I/O ports
• Active LOW reset input (RESET)
• Open-drain active LOW interrupt output (INT)
• 400 kHz Fast-mode I2C-bus
• Internal power-on reset
• Power-up with all channels configured as inputs
• No glitch on power-up
• 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
• ESD protection exceeds JESD 22
– 2000 V Human-Body Model (A114-A)
– 1000 V Charged-Device Model (C101)
• Packages offered: TSSOP24, HWQFN24, VFBGA24, X2QFN24 (LGA, Land Grid

Applicazione
- Microcontroller-Based Systems: They are used to expand the number of digital I/O pins available to microcontrollers, especially in cases where the microcontroller's native pins are insufficient.
- Keypad and Button Interfaces: GPIO expanders are commonly used to interface with keypads and push-button arrays.
- LED and Display Control: They can control the state of LEDs, LCD displays, and other digital indicators.
- Sensor Interfaces: GPIO expanders can be used to interface with digital sensors and read their state or control their functionality.
- Industrial Automation: These devices find use in industrial automation systems for controlling various actuators and sensors.
- Automotive Electronics: They are used in automotive systems for tasks like controlling lighting, sensors, and user interface components.
- Home Automation: GPIO expanders are employed in smart home and IoT (Internet of Things) devices for controlling lights, switches, and other home automation features.
- Medical Devices: They are used in medical equipment for control and monitoring functions.
