Infineon Technologies CY9BF116RPMC-G-JNE2

Overview

CY9BF116RPMC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller designed for motor control and industrial embedded systems. It operates up to 144 MHz, integrates 512 KB MainFlash with Flash Accelerator, 32 KB WorkFlash, 64 KB SRAM (split into SRAM0/SRAM1), and features dual 12-bit ADCs (16 channels total), eight base timers, three QPRC channels, and LIN/UART/I²C/CSIO serial interfaces.

For engineers reviewing the CY9BF116RPMC-G-JNE2 datasheet, CY9BF116RPMC-G-JNE2 pinout, CY9BF116RPMC-G-JNE2 application, or CY9BF116RPMC-G-JNE2 equivalent, this device supports real-time motor control timing, high-precision analog sensing, deterministic interrupt handling via NVIC (48 peripheral interrupts), and secure code protection across dual Flash banks - critical for automotive body control modules and industrial PLC I/O units.

Technical Context

The CY9BF116RPMC-G-JNE2 implements an Arm Cortex-M3 r2p1 core with Memory Protection Unit (MPU) and integrated NVIC supporting 16 priority levels, NMI, and 48 peripheral interrupts. Its clock system includes five sources (4–48 MHz main oscillator, 32.768 kHz sub-clock, 4 MHz/100 kHz internal CR oscillators, and Main PLL), managed by Clock Supervisor (CSV) for external clock failure detection.

Peripheral architecture is segmented: three independent A/D converters (12-bit SAR, 1.0 μs conversion @5 V), eight-channel DMA with 32-bit addressing, and dedicated motor control blocks including QPRC (16-bit position/revolution counters), multi-function timers with dead-time insertion, and DTIF emergency stop interrupt - all synchronized to precise base timer events.

FAQ

What is the maximum operating frequency and supported clock sources?

The CY9BF116RPMC-G-JNE2 operates up to 144 MHz using its Main PLL, which accepts input from either a 4–48 MHz external crystal (XTAL/EXTAL) or the 4 MHz internal CR oscillator. Five clock sources are available: main oscillator, 32.768 kHz sub-clock, two internal CR oscillators (4 MHz and 100 kHz), and the PLL output. Clock Supervisor monitors external oscillator stability and triggers reset on failure.

Does this MCU support LIN communication natively, and what protocol versions are implemented?

Yes, the CY9BF116RPMC-G-JNE2 includes hardware LIN controllers compliant with LIN Protocol Specification v2.1. Each LIN channel supports master/slave mode, configurable break field length (13–16 bits), break delimiter (1–4 bits), and built-in error detection for framing, parity, and overrun conditions - eliminating need for external transceivers or software protocol stacks.

How is Flash memory organized, and what security features protect firmware?

It features dual on-chip Flash: 512 KB MainFlash for executable code and 32 KB WorkFlash for data logging or firmware updates. Both share hardware-based code protection (lock bits), preventing unauthorized read/write access. The Flash Accelerator enables zero-wait-state access up to 72 MHz, and maintains equivalent performance above that frequency via trace buffer caching.

What low-power modes are available, and how does wake-up from Stop mode work?

Three low-power modes are supported: Sleep (CPU halted, peripherals active), Timer (CPU stopped, RTC/watch counter running), and Stop (all clocks halted except sub-clock). Wake-up from Stop mode is triggered by the Watch Counter - a dedicated 32-bit down-counter driven by the 32.768 kHz sub-clock, configurable for intervals up to 64 seconds with automatic reload.
