Infineon Technologies CY8C4147AZAS568XQLA1

Overview

CY8C4147AZAS568XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Max microcontroller based on the Arm® Cortex®-M0+ CPU running at 48 MHz, featuring 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. It targets body control modules and smart sensor nodes requiring reconfigurable analog/digital logic and functional safety support.

For engineers reviewing the CY8C4147AZAS568XQLA1 datasheet, CY8C4147AZAS568XQLA1 pinout, CY8C4147AZAS568XQLA1 application, or CY8C4147AZAS568XQLA1 equivalent, key selection considerations include CAN FD timing compliance, Deep Sleep current (2.5 µA), MSC water-tolerance capability, programmable Smart I/O routing, and ModusToolbox™ API compatibility for rapid CAPSENSE™ and TCPWM configuration.

Technical Context

The device implements a single-layer AHB-Lite interconnect between the Cortex-M0+ core, memory subsystem (384 KB flash + 32 KB SRAM), and peripherals including five reconfigurable Serial Communication Blocks (SCBs), eight TCPWM units with quadrature decode and kill-signal triggering, and a dedicated CAN FD controller supporting ISO 11898-1:2015 with bit rates up to 5 Mbps. Clocking includes ECO (4–33 MHz) with PLL, WCO (32 kHz), IMO (±2%), and ILO (40 kHz).

Analog resources comprise two CTBm opamps (operable in Deep Sleep), two low-power comparators, SAR ADC with temperature sensor and channel sequencer, and MSC block enabling hardware-accelerated capacitive sensing with SmartSense auto-tuning. Digital programmability extends to Smart I/O logic and Boolean operations on GPIO paths without CPU intervention.

FAQ

Does CY8C4147AZAS568XQLA1 support CAN FD ISO 11898-1:2015 conformance testing?

Yes. The integrated CAN FD block complies with ISO 11898-1:2015, supporting data rates up to 5 Mbps, flexible data length (up to 64 bytes), and CRC-17/CRC-21 error detection. Hardware features include bit-rate switching, automatic retransmission, and loopback self-test mode - validated in Infineon's AEC-Q100 qualification report Rev G.

What is the maximum operating frequency of the internal main oscillator (IMO)?

The IMO operates at a nominal 48 MHz with ±2% accuracy across –40°C to +105°C and 1.71–5.5 V supply range. It serves as the default clock source at power-up and can be used directly for low-jitter peripherals like TCPWM or SCB, eliminating need for external crystal in cost-sensitive designs.

Can all 84 GPIO pins be simultaneously configured for CAPSENSE™ electrode function?

No. While any GPIO pin can be assigned to CAPSENSE™, the MSC block supports up to 32 electrodes per scan group, and total electrode count is limited by SAR ADC channel count, routing resources, and mutual-capacitance scan time. Practical implementations use 16–24 electrodes with SmartSense auto-tuning for optimal SNR and response time.

Is ModusToolbox™ required to configure the programmable analog blocks?

No. ModusToolbox™ provides graphical configuration and auto-generated PDL APIs, but low-level register access is fully documented in the PSoC™ 4100S Max TRM (002-30041 Rev *G). Engineers may implement custom analog routing and CTBm opamp configurations directly via memory-mapped registers for deterministic timing-critical applications.
