Infineon Technologies CY9BF412RPMC-G-JNE2

Overview

CY9BF412RPMC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 512 KB MainFlash, 32 KB WorkFlash, 64 KB SRAM, dual CAN 2.0A/B interfaces (up to 1 Mbps), and integrated motor control peripherals including QPRC, multi-function timers, and A/D converters. It operates at up to 144 MHz, supports 2.7–5.5 V supply, and targets real-time embedded motor control systems in industrial drives and automotive body electronics.

For engineers reviewing the CY9BF412RPMC-G-JNE2 datasheet, CY9BF412RPMC-G-JNE2 pinout, CY9BF412RPMC-G-JNE2 application, or CY9BF412RPMC-G-JNE2 equivalent, key selection criteria include its dual-CAN capability, 12-bit ADC with 1.0 μs conversion time, 103 GPIOs in 120-pin LQFP package, Flash accelerator enabling zero-wait-state operation up to 72 MHz, and hardware watchdog with independent CR oscillator for fail-safe operation.

Technical Context

The CY9BF412RPMC-G-JNE2 implements an Arm Cortex-M3 r2p1 core with Memory Protection Unit (MPU) and NVIC supporting 48 peripheral interrupts across 16 priority levels. Its dual Flash architecture separates executable code (MainFlash) from configuration/data storage (WorkFlash), each with distinct wait-state behavior and shared security protection.

Peripheral integration includes three QPRC channels for encoder position tracking, eight base timers configurable as PWM/PPG/reload counters, and a DMA controller with eight independent channels supporting burst/block transfers across 4 GB address space - all synchronized to the 144 MHz system clock derived from main PLL or internal oscillators.

FAQ

What is the maximum operating frequency and how is it achieved?

The CY9BF412RPMC-G-JNE2 achieves up to 144 MHz system clock using its main PLL with external crystal (4–48 MHz) as input. The PLL supports fractional multiplication and is internally calibrated. Flash accelerator ensures zero-wait-state execution up to 72 MHz and maintains effective performance beyond via prefetch and trace buffer - verified in Rev. *F datasheet Section 12.4.4.

Does this MCU support functional safety standards like ISO 26262?

The CY9BF412RPMC-G-JNE2 includes hardware features aligned with ASIL-B requirements: Memory Protection Unit (MPU), dual watchdog timers (hardware and software), Clock Supervision (CSV), Low-Voltage Detector (LVD), and CRC accelerator. While not pre-certified, it serves as a foundation for ISO 26262-compliant designs per Infineon's FM3 Functional Safety Manual (Doc. No. 002-05616).

How many independent CAN controllers does it have, and what protocol versions are supported?

It integrates two fully independent CAN controllers compliant with ISO 11898-1:2015 (CAN 2.0A/B), supporting both standard (11-bit) and extended (29-bit) identifiers, bit rates up to 1 Mbps, and built-in 32-message buffer FIFOs per channel - confirmed in Section 3.3 of the datasheet.

Is the WorkFlash memory suitable for EEPROM emulation, and what endurance is guaranteed?

Yes, the 32 KB WorkFlash supports EEPROM emulation via Infineon's FM3 Flash Library (FLIB), which implements wear-leveling and atomic write routines. Endurance is rated at 100,000 erase/write cycles per sector, with data retention of 20 years at 85°C - specified in the FM3 Peripheral Manual (Doc. No. 002-05617), TYPE4 section.
