CY8C21645-24PVXAT

Overview

The CY8C21645-24PVXAT is an 8-bit microcontroller from the Cypress PSOC 1 family, utilizing the M8C core. It features 8KB of in-system programmable flash memory and 512 bytes of RAM. The device operates at a maximum clock frequency of 24MHz with an internal oscillator. It supports a supply voltage range of 3V to 5.25V and includes three 10-bit analog-to-digital converters. The component is housed in a 28-pin SSOP package and is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

Integrates mixed-signal capabilities with programmable analog blocks and digital interconnects within a single chip architecture.
Provides flexible GPIO configuration through a comprehensive set of digital peripherals including UART, SPI, I2C, and PWM modules.
Supports CapSense technology for capacitive touch sensing applications without requiring external components.

Applications

Capacitive touch control interfaces for consumer electronics
Battery-powered embedded systems requiring low power consumption
Industrial controllers utilizing mixed-signal processing

Procurement Notes

Verify the specific suffix 'PVXAT' against official Cypress documentation to confirm package type, temperature grade, and tape-and-reel specifications. Ensure compatibility with design-in requirements regarding pinout and electrical characteristics before procurement.

Selection Notes

Select this component when an 8-bit MCU with integrated analog functionality and CapSense support is required. Compare pin counts and memory sizes against other PSOC 1 variants like the CY8C21x34 series if fewer peripherals are needed. Confirm voltage and temperature ranges match the target application environment.

Part Context

This part belongs to the PSOC 1 CY8C21xxx series, designed for cost-sensitive mixed-signal applications. It combines a fast 8-bit processor with programmable analog blocks, allowing designers to replace multiple discrete components with a single IC solution.

Replacement Considerations

Check for direct substitutes within the CY8C21xxx family such as CY8C21645-24PVXI or CY8C21645-24LTXI, ensuring package and temperature ratings align. Verify that any alternative maintains the same flash size and peripheral count.
