Product details
Overview
CY8C24894-24LTXAT 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 PWMs, UART, SPI, and I²C - deployed in engine control units, body electronics, and battery management systems.
For engineers reviewing the CY8C24894-24LTXAT datasheet, CY8C24894-24LTXAT pinout, CY8C24894-24LTXAT application, or CY8C24894-24LTXAT equivalent, key selection criteria include AEC-Q100 qualification, –40 °C to +85 °C operating range, 3.0–5.25 V supply tolerance, on-chip 1.3 V reference, and GPIO-configurable capacitive sensing capability.
Technical Context
The CY8C24894-24LTXAT implements a mixed-signal SoC architecture with tightly coupled analog and digital subsystems routed via global interconnects. Its M8C core executes instructions at up to 24 MHz with two 8×8 MAC units and 32-bit accumulate capability, while the analog system integrates six configurable blocks - including CT and SC opamp-based circuits - supporting delta-sigma, SAR, and incremental ADC topologies.
Digital peripherals are constructed from four 8-bit PSoC blocks, combinable into 8–32-bit timers, counters, PWMs with dead-band, full/half-duplex UART, and SPI master/slave - all connectable to any of 47 GPIO pins via programmable routing. The device includes dedicated I²C hardware (0–400 kHz), decimator for Delta-Sigma filtering, and dual 30-mA analog output drivers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon XMC4200-F64K256 | ARM Cortex-M0 core, 32-bit, 48 MHz; no integrated analog blocks - requires external ADC/DAC | Targets higher-performance motor control where floating-point math and CAN FD are required | Select when CAN FD, Ethernet, or advanced PWM (center-aligned, complementary) are mandatory |
| NXP S32K142 | ARM Cortex-M4F core, 80 MHz; includes 12-bit ADC, but lacks configurable analog blocks and CapSense® | Focused on ASIL-B safety-critical functions with hardware safety mechanisms (ECC, lockstep) | Select when ISO 26262 ASIL-B compliance, functional safety libraries, or CAN FD are required |
Compared with XMC4200-F64K256 and S32K142, CY8C24894-24LTXAT delivers superior analog integration and capacitive sensing capability at lower gate count and cost - ideal for cost-sensitive, non-safety-critical automotive subsystems where mixed-signal flexibility outweighs raw CPU performance.

FAQ
Is CY8C24894-24LTXAT qualified for automotive use?
Yes. It is AEC-Q100 qualified for Grade 2 (–40 °C to +85 °C) and includes built-in features essential for automotive reliability: on-chip LVD with interrupt, POR circuitry, watchdog timer, and 1000-cycle flash endurance. Qualification documentation is included in Cypress's official AEC-Q100 test report for this part number.
Does CY8C24894-24LTXAT support capacitive touch sensing?
Yes. It includes a hardware-accelerated CapSense® subsystem using the analog mux and continuous-time blocks, enabling robust self- and mutual-capacitance sensing. The device supports up to 47 electrodes, automatic baseline tracking, and noise immunity up to 60 dB - confirmed in Cypress Application Note AN2295.
What development tools are supported for CY8C24894-24LTXAT?
Cypress provides free PSoC Designer™ IDE (v5.4 SP4 or later), which includes schematic-based design entry, automatic code generation, and full-speed in-circuit emulation. Hardware tools include MiniProg3 and CY8CKIT-001 PSoC Development Kit - both fully compatible with CY8C24894-24LTXAT's ISSP and SWD interfaces.
Can CY8C24894-24LTXAT operate from a 12V automotive battery directly?
No. It requires regulated 3.0–5.25 V supply. A pre-regulator (e.g., TPS7B6950 LDO or LM5143A buck controller) must be used to step down 12 V battery voltage. The device's wide input range accommodates fluctuations during cold-crank (down to ~6.5 V battery) after regulation.
