Infineon Technologies CY8C4147AZAS588XQLA1

Overview

CY8C4147AZAS588XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade PSoC™ 4100S Max microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 384 KB flash, 32 KB SRAM, integrated CAN FD (up to 5 Mbps), 12-bit 1-Msps SAR ADC, and multi-sense capacitive sensing (MSC) with >5:1 SNR for touch interfaces in harsh environments.

For engineers reviewing the CY8C4147AZAS588XQLA1 datasheet, CY8C4147AZAS588XQLA1 pinout, CY8C4147AZAS588XQLA1 application, or CY8C4147AZAS588XQLA1 equivalent, key selection considerations include CAN FD timing compliance, Deep Sleep current (2.5 µA), programmable analog routing, CAPSENSE™ SmartSense auto-tuning, and 84-GPIO flexibility across 100-pin TQFP packaging.

Technical Context

The device implements a single-layer AHB-Lite interconnect between CPU, memory, and peripherals, supporting concurrent DMA transfers and low-latency peripheral access. Its analog subsystem integrates two reconfigurable opamps (with Deep Sleep operation), two low-power comparators, and a temperature-sensor-coupled SAR ADC with hardware channel sequencing and signal averaging.

Digital resources include eight 16-bit TCPWM blocks with quadrature decode and comparator-triggered kill signals, five reconfigurable SCBs (I²C/SPI/UART/LIN), and a dedicated CAN FD controller compliant with ISO 11898-1:2015 with bit-rate switching up to 5 Mbps - all operating under deterministic timing control from multiple clock sources including ECO+PLL, WCO, and IMO.

FAQ

What is the maximum operating temperature grade for CY8C4147AZAS588XQLA1?

This part is qualified to AEC-Q100 Grade-S, with guaranteed operation from –40°C to +105°C ambient temperature. It is not rated for Grade-E (+125°C) operation. Thermal derating must be applied if used near package thermal limits, and junction temperature must remain below 150°C under all operating conditions per datasheet Section 7.2.1.

Does CY8C4147AZAS588XQLA1 support CAN FD bit-rate switching?

Yes - the integrated CAN FD controller complies with ISO 11898-1:2015 and supports bit-rate switching, enabling arbitration phase at 1 Mbps and data phase up to 5 Mbps. Configuration is done via ModusToolbox™ CAN FD middleware, and hardware filtering and message RAM are fully configurable for automotive diagnostic and control messaging.

Can all 84 GPIOs be used simultaneously for CAPSENSE™ sensing?

No - while any GPIO can be assigned to CAPSENSE™, the MSC block supports up to 64 electrodes per scan group, and total electrode count is limited by SAR ADC channel count and scan time budget. Simultaneous use of all 84 pins requires segmentation into multiple scan groups with sequential execution, managed by the CAPSENSE™ middleware.

Is external crystal required for CAN FD operation?

No - CAN FD timing accuracy relies on the internal IMO (±2%) or ECO (±50 ppm) oscillator. For full ISO 11898-1 compliance at 5 Mbps, Infineon recommends using the 4–33 MHz ECO with PLL; the IMO alone does not meet bit-timing jitter requirements for high-speed data phase operation.
