Infineon Technologies CY9AF116MAPMC-GNCGE2

Overview

CY9AF116MAPMC-GNCGE2 from Infineon Technologies (formerly Cypress Semiconductor) is a 32-bit Arm® Cortex-M3 microcontroller designed for motor control and industrial embedded applications. It features a 40 MHz CPU, 512 KB on-chip flash with zero-wait-state access, 32 KB SRAM (split into two 16 KB banks), integrated 12-bit ADC with up to 16 channels, and dual multifunction timers supporting PWM generation, input capture, and A/D trigger synchronization.

For engineers reviewing the CY9AF116MAPMC-GNCGE2 datasheet, CY9AF116MAPMC-GNCGE2 pinout, CY9AF116MAPMC-GNCGE2 application, or CY9AF116MAPMC-GNCGE2 equivalent, key selection criteria include its 100-pin LQFP package with 83 high-speed I/Os, hardware CRC accelerator (CCITT CRC16/IEEE-802.3 CRC32), dual watchdog timers (SW + HW), and support for LIN 2.1, UART, I²C, and CSIO protocols in up to eight serial channels.

Technical Context

This MCU implements the Arm Cortex-M3 r2p1 core with nested vector interrupt controller (NVIC) supporting 48 peripheral interrupts and 16 priority levels. Its memory subsystem includes separate I-Code/D-Code buses for SRAM0 and System bus for SRAM1, enabling concurrent instruction fetch and data access.

The peripheral set is optimized for real-time motor control: dual multifunction timers provide 3× free-running counters, 4× input capture, 6× output compare, and 3× A/D start triggers per unit; QPRC units support quadrature encoder position sensing with 16-bit counters and dual compare registers; and DMA controller supports 8-channel burst/transfer modes across full 32-bit address space.

FAQ

What is the maximum operating frequency and supported voltage range for CY9AF116MAPMC-GNCGE2?

The CY9AF116MAPMC-GNCGE2 operates at a maximum CPU frequency of 40 MHz and supports a wide supply voltage range of 2.7 V to 5.5 V. This range accommodates both 3.3 V industrial logic and 5 V legacy automotive interfaces, while the 40 MHz clock enables real-time execution of motor control algorithms with sub-microsecond timing resolution.

Does CY9AF116MAPMC-GNCGE2 support hardware LIN communication, and which revision is implemented?

Yes, CY9AF116MAPMC-GNCGE2 supports hardware LIN communication compliant with LIN Protocol Specification Revision 2.1. The integrated multifunction serial interface (MFS) provides dedicated LIN master and slave modes, including break field generation (13–16 bits), break delimiter control (1–4 bits), and automatic checksum calculation - all handled in hardware without CPU intervention.

How many ADC channels and what resolution does the on-chip analog-to-digital converter provide?

The device integrates a 12-bit successive-approximation ADC with up to 16 input channels, organized across three independent units. Conversion time is 1.0 μs at 5 V supply, and it supports scan mode with 16-deep FIFO and priority-based conversion with 4-deep FIFO - enabling simultaneous sampling of motor phase currents and temperature sensors in real-time control loops.

What debug interface is supported, and is JTAG fully available?

CY9AF116MAPMC-GNCGE2 supports Serial Wire JTAG Debug Port (SWJ-DP), which combines SWD and JTAG functionality on shared pins. Full JTAG boundary-scan is available, but the device does not implement Embedded Trace Macrocell (ETM); trace capability is limited to SWO (Serial Wire Output) for program flow and data tracing via the SWD interface.
