Infineon Technologies CY8C24894-24LTXA

Overview

CY8C24894-24LTXA from Cypress Semiconductor is an AEC-Q100 qualified automotive-grade programmable system-on-chip (PSoC®) featuring an M8C 8-bit Harvard architecture CPU running at up to 24 MHz, 16 KB flash, 1 KB SRAM, six configurable analog blocks (supporting up to 14-bit ADCs and 9-bit DACs), and four digital PSoC blocks (enabling UART, SPI, I²C, PWM, and CRC). It operates from 3.0 V to 5.25 V across –40 °C to +85 °C and is used in vehicle body control modules for sensor signal conditioning and real-time actuator control.

For engineers reviewing the CY8C24894-24LTXA datasheet, CY8C24894-24LTXA pinout, CY8C24894-24LTXA application, or CY8C24894-24LTXA equivalent, key selection criteria include AEC-Q100 qualification, on-die analog configurability (PGA, filter, comparator), dual 30-mA analog outputs, 47-channel analog input muxing, and ISSP-enabled field firmware updates.

Technical Context

The CY8C24894-24LTXA integrates a deterministic M8C core with two independent hardware MAC units (8×8 multiply + 32-bit accumulate), enabling real-time digital filtering without CPU overhead. Its analog system uses three continuous-time (CT) and three switched-capacitor (SC) blocks arranged in columnar topology, supporting simultaneous dual-channel delta-sigma ADC conversion via split analog mux bus.

Digital peripherals are constructed from four 8-bit PSoC blocks interconnected via global digital routing, allowing synthesis of 32-bit timers, dead-band PWMs, and full-duplex UARTs-all configurable to any GPIO. Clocking includes a ±4% 24 MHz IMO (doublable to 48 MHz), a 32 kHz ILO for low-power sleep, and programmable dividers routed to both analog and digital subsystems.

FAQ

Is CY8C24894-24LTXA pin-compatible with other CY8C24x94 variants?

Yes - all CY8C24x94 devices in the 56-pin LQFP package share identical pinouts and footprint. Differences lie in flash size, SRAM allocation, and analog/digital block counts, but mechanical and electrical I/O compatibility is maintained across the family for design reuse and migration.

Does CY8C24894-24LTXA support capacitive touch sensing out of the box?

Yes - it includes dedicated continuous-time analog blocks, a programmable analog mux with precharge control, and hardware-accelerated baseline tracking algorithms. Cypress's CapSense® user module in PSoC Designer provides certified firmware libraries for button, slider, and proximity sensing compliant with IEC 61000-4-6.

What clock sources are available for low-power sleep modes?

The device integrates a 32 kHz internal low-speed oscillator (ILO) dedicated to sleep timer and watchdog operation. This oscillator draws <1 µA and remains active during deep-sleep modes, enabling wake-up intervals from 1 ms to 2.1 seconds without external components.

Can the 16 KB flash be updated in-system without erasing the entire memory?

Yes - the CY8C24894-24LTXA supports partial flash updates via ISSP. Flash is organized in 64-byte rows, and protection levels can be set per row. This enables patching firmware, updating calibration tables, or modifying configuration parameters without disrupting operational code or risking full memory corruption.
