Infineon Technologies CY9AF116MAPMC-G-MNE2

Overview

CY9AF116MAPMC-G-MNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 512 KB on-chip Flash, 32 KB SRAM (split into two 16 KB banks), 100-pin LQFP package, and integrated motor control peripherals including 8-channel Base Timers, 3-unit 12-bit ADC (16 channels), and QPRC for encoder position sensing. It operates from 2.7 V to 5.5 V at up to 40 MHz and targets industrial motor drives and embedded control systems requiring deterministic real-time response.

For engineers reviewing the CY9AF116MAPMC-G-MNE2 datasheet, CY9AF116MAPMC-G-MNE2 pinout, CY9AF116MAPMC-G-MNE2 application, or CY9AF116MAPMC-G-MNE2 equivalent, key selection criteria include its dual-bank SRAM architecture for concurrent code/data access, hardware CRC accelerator (CCITT CRC16/IEEE-802.3 CRC32), external bus interface supporting 256 MB address space, and SWJ-DP debug interface without ETM.

Technical Context

This MCU implements a tightly coupled Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus a 24-bit SysTick timer for OS scheduling. Its memory subsystem features zero-wait-state Flash execution and separate I-code/D-code buses for SRAM0, enabling simultaneous instruction fetch and data access.

The peripheral set includes an 8-channel DMA controller with independent bus arbitration, multi-function serial interfaces (8 channels total - UART/CSIO/LIN/I²C with configurable FIFO depth), and dedicated motor control blocks: dual QPRC units for quadrature decoding, DTIF emergency stop interrupt, and waveform generators with dead-time insertion capability.

FAQ

What debug interface does CY9AF116MAPMC-G-MNE2 support?

CY9AF116MAPMC-G-MNE2 supports Serial Wire JTAG Debug Port (SWJ-DP) only - it does not include Embedded Trace Macrocell (ETM). Debugging uses standard ARM CoreSight protocol over SWD or JTAG, with TRSTX, TCK, TMS, TDI, and TDO pins mapped to P00–P04. Trace output is limited to SWO (Serial Wire Output) on P04.

Does this MCU support external memory expansion?

Yes - CY9AF116MAPMC-G-MNE2 includes a full External Bus Interface (EBI) supporting up to 8 chip selects, 25-bit addressing (256 MB), 8-/16-bit data width, address/data multiplexing, and external RDY handshake. It interfaces directly with SRAM, NOR Flash, and other memory-mapped peripherals without external glue logic.

How many ADC channels and what resolution does it offer?

CY9AF116MAPMC-G-MNE2 integrates three 12-bit successive approximation ADC units totaling 16 input channels. Conversion time is 1.0 μs at 5 V supply. Each unit supports scanning mode with 16-step FIFO and priority conversion with 4-step FIFO, enabling synchronized sampling across multiple sensors in motor control loops.

Is the QPRC feature available on all package variants?

Yes - Quadrature Position/Revolution Counter (QPRC) is implemented in silicon and available on all CY9AF116x variants, including CY9AF116MAPMC-G-MNE2 in 100-pin LQFP. Two independent QPRC units are provided, each with 16-bit position and revolution counters, configurable edge detection on AIN/BIN/ZIN, and dual compare registers for index pulse matching.
