Infineon Technologies CY9BF168RPMC-G-MNE2

Overview

CY9BF168RPMC-G-MNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M4F microcontroller with integrated 1024 KB Flash, 128 KB SRAM (64 KB + 32 KB + 32 KB), and motor control peripherals including dual QPRC, 8-channel base timers, and LIN/UART/CSIO/I²C interfaces. It operates up to 160 MHz with FPU, MPU, and hardware CRC acceleration, targeting real-time embedded motor control systems.

For engineers reviewing the CY9BF168RPMC-G-MNE2 datasheet, CY9BF168RPMC-G-MNE2 pinout, CY9BF168RPMC-G-MNE2 application, or CY9BF168RPMC-G-MNE2 equivalent, key selection criteria include its 120-pin LQFP package, 2.7–5.5 V supply range, dual 12-bit ADCs (24 channels total), 2×12-bit DACs, and deep-standby RTC mode with VBAT support for battery-backed operation.

Technical Context

The CY9BF168RPMC-G-MNE2 implements a single ARM Cortex-M4F core (r0p1 revision) with tightly coupled instruction and data buses, supporting DSP instructions and a Memory Protection Unit (MPU) for system reliability. Its clock system integrates five sources - main oscillator (4–48 MHz), sub-clock (32.768 kHz), two internal CR oscillators, and a programmable Main PLL - enabling dynamic frequency scaling and low-power mode transitions.

Peripheral subsystems are organized around dedicated bus bridges: the External Bus Interface supports NAND/SRAM/SDRAM with scramble-enabled address ranges; DSTC provides descriptor-driven DMA offloading across 128 channels; and the Multi-function Timer unit delivers 6.25 ns resolution for PWM, dead-time insertion, and A/D activation triggers in motor control loops.

Key Specifications

FAQ

What is the maximum operating frequency and supported voltage range?

CY9BF168RPMC-G-MNE2 operates at up to 160 MHz with a supply voltage range of 2.7 V to 5.5 V for both VCC and VBAT. The core achieves wait-state-free Flash access up to 72 MHz; above that, the integrated Flash Accelerator maintains equivalent performance. All I/Os are rated for 5V tolerance on designated pins, simplifying interface with legacy 5 V logic and sensors.

Does this MCU support LIN communication natively?

Yes - CY9BF168RPMC-G-MNE2 includes two dedicated LIN channels compliant with LIN 2.1 specification, supporting both master and slave modes. Each channel provides hardware break field generation (13–16 bit), break delimiter control (1–4 bit), and automatic error detection (framing, parity, overrun). No external transceiver is needed for basic LIN node implementation.

How many ADC channels and what resolution does it offer?

The device integrates three independent 12-bit successive approximation ADC units totaling 24 input channels. Conversion time is 0.5 µs at 5 V supply, with priority-based and scanning modes supported. Each ADC includes a dedicated FIFO (16-step for scan, 4-step for priority), enabling synchronized sampling across multiple motor phases without CPU intervention.

Is there hardware support for functional safety features?

CY9BF168RPMC-G-MNE2 includes several hardware features aligned with IEC 61508 SIL2 and ISO 26262 ASIL-B requirements: Memory Protection Unit (MPU), dual watchdog timers (hardware and software), Clock Supervision (CSV) for external oscillator failure detection, Low-Voltage Detector (LVD2) with auto-reset, and DTIF (motor emergency stop) hardware interrupt. These are documented in Infineon's FM4 Functional Safety Manual (002-05022).
