Product details
Overview
CY8C21534-24PVXAT from Cypress Semiconductor is an AEC-Q100 qualified automotive-grade PSoC® programmable system-on-chip featuring an 8-bit M8C Harvard-architecture CPU running at up to 24 MHz, 8 KB flash, 512 bytes SRAM, and four configurable analog + four digital PSoC blocks for mixed-signal embedded control in body electronics and sensor interface modules.
For engineers reviewing the CY8C21534-24PVXAT datasheet, CY8C21534-24PVXAT pinout, CY8C21534-24PVXAT application, or CY8C21534-24PVXAT equivalent, key selection criteria include its –40 °C to +85 °C operating range, 3.0–5.25 V supply, integrated 10-bit ADC with DAC-referenced comparators, and GPIO-configurable capacitive sensing capability for touch HMI systems.
Technical Context
The CY8C21534-24PVXAT implements a fixed-function M8C core with Harvard architecture, supporting up to 24 MHz operation and 4 MIPS throughput. Its digital system comprises four 8-bit PSoC blocks configurable as timers, PWMs (8–32 bit), UART, SPI, I²C (up to 400 kHz), CRC, and PRS generators - all routable to any of 28 GPIOs via global digital interconnect.
The analog system integrates four Type E PSoC blocks: two support comparators with 1.3 V or 8-bit DAC reference, and two enable single/dual 10-bit SAR ADCs with up to 24 channels. An on-chip 1.3 V precision voltage reference and flexible analog mux bus enable hardware-accelerated capacitive sensing without external components.

FAQ
Is CY8C21534-24PVXAT pin-compatible with CY8C21434-24PVXIT?
Yes, both parts share identical 28-pin SSOP packaging and pin mapping, including VDD, VSS, RESET, SWD, XIN/XOUT, and all GPIO assignments. The only difference is automotive qualification and associated test screening-no layout or schematic changes are needed when upgrading from industrial to automotive grade.
Does CY8C21534-24PVXAT support capacitive sensing without external components?
Yes-it integrates a dedicated analog mux bus and Type E analog blocks with hardware-accelerated charge-transfer timing, enabling self-capacitance and mutual-capacitance sensing directly on any GPIO. No external resistors, capacitors, or op-amps are required for basic touch button or slider implementation.
What development tools are required to program CY8C21534-24PVXAT?
PSoC Designer™ IDE (legacy, Windows-only) is the official toolchain, supporting component configuration, C code generation, and ISSP programming via MiniProg1 or USB-based ICE. Debugging requires the CY3210-PSoCEVAL1 development kit or compatible in-circuit emulator with SWD interface support.
Can CY8C21534-24PVXAT operate from a 3.3 V supply in automotive environments?
Yes-the device supports 3.0 V to 5.25 V operation across its full automotive temperature range (–40 °C to +85 °C). At 3.3 V, the internal 24 MHz IMO remains stable, and all GPIOs maintain 25 mA sink capability, making it suitable for 3.3 V CAN/LIN node power domains with appropriate LDO regulation.
