Infineon Technologies CY8C24894-24LFXA

Overview

CY8C24894-24LFXA from Cypress Semiconductor is an AEC-Q100 qualified automotive-grade programmable system-on-chip featuring an M8C 8-bit Harvard-architecture CPU running at up to 24 MHz, 16 KB flash, 1 KB SRAM, six configurable analog PSoC blocks (supporting up to 14-bit ADCs and 9-bit DACs), and four digital PSoC blocks (including 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 automotive body control modules for sensor signal conditioning and real-time actuator control.

For engineers reviewing the CY8C24894-24LFXA datasheet, CY8C24894-24LFXA pinout, CY8C24894-24LFXA application, or CY8C24894-24LFXA equivalent, key selection criteria include AEC-Q100 qualification, integrated analog/digital reconfigurable blocks, 24-MHz IMO ±4% accuracy, GPIO drive strength (25 mA sink / 10 mA source), and support for capacitive touch sensing via analog mux and CT/SC blocks.

Technical Context

The CY8C24894-24LFXA implements a mixed-signal SoC architecture with separate global digital and analog interconnects, enabling dynamic routing of signals between its four digital PSoC blocks and six analog PSoC blocks. Its M8C core executes instructions at up to 24 MHz with two 8×8 multipliers and 32-bit accumulate units, supporting real-time control loops and digital filtering.

Dedicated hardware resources include a 24-MHz internal main oscillator (IMO) with ±4% tolerance over voltage and temperature, a 32-kHz internal low-speed oscillator (ILO) for sleep/wake timing, dual MAC units for fast DSP operations, and a decimator block optimized for Delta-Sigma ADC implementation - all accessible without CPU intervention.

FAQ

What development tools are required to program the CY8C24894-24LFXA?

PSoC Designer™ 5.4 is the official IDE for this device, providing schematic-based user module configuration, automatic code generation, and full-speed in-circuit emulation via MiniProg1 or MiniProg3 programmers. No third-party toolchains are supported - firmware must be compiled using Cypress's proprietary assembler and linker targeting the M8C core.

Does the CY8C24894-24LFXA support true hardware I²C master mode?

Yes - it includes a dedicated I²C hardware block supporting standard-mode (100 kHz) and fast-mode (400 kHz) operation as master, slave, or multimaster. Unlike bit-banged implementations, this block handles arbitration, clock stretching, and ACK/NACK automatically without CPU overhead or timing jitter.

Can the analog blocks operate independently while the CPU is in deep-sleep mode?

Yes - analog blocks retain configuration and continue sampling via autonomous triggers (e.g., timer or LFO) while the M8C core is halted. The decimator and PGA remain active, allowing continuous low-power sensor monitoring with wake-on-threshold interrupt - verified in datasheet Section 12.3 (Low-Power Modes).

Is the 24-MHz internal oscillator calibrated at production?

No - the 24-MHz IMO has ±4% initial accuracy across voltage and temperature, with no factory calibration. For applications requiring tighter timing (e.g., UART baud rate stability), designers must use the internal PLL to lock to an external crystal or calibrate against a known reference using the IMO trim register (IMO_TRIM), as documented in Register Map Bank 1.
