Infineon Technologies CY9AF116NPMC-G-MNE1

Overview

CY9AF116NPMC-G-MNE1 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 operation up to 40 MHz. It integrates motor control timers, 16-channel 12-bit ADC (1.0 µs conversion @5 V), 8-channel DMA, and multi-protocol serial interfaces (UART/CSIO/LIN/I²C) for embedded motor control and industrial automation systems.

For engineers reviewing the CY9AF116NPMC-G-MNE1 datasheet, CY9AF116NPMC-G-MNE1 pinout, CY9AF116NPMC-G-MNE1 application, or CY9AF116NPMC-G-MNE1 equivalent, key selection criteria include Flash/SRAM size, peripheral count (e.g., 8 base timers, 2 QPRC units), external bus interface support (25-bit address, 8 chip selects), and 5V-tolerant I/O capability in this specific variant.

Technical Context

This MCU implements the Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus a 24-bit SysTick timer for RTOS integration. Its memory subsystem features zero-wait-state Flash execution and dual-bus-connected SRAM banks (SRAM0 on I/D-code bus, SRAM1 on system bus) enabling concurrent CPU and DMA access.

The peripheral set includes an 8-channel multi-function serial interface (4 with 16×9-bit FIFO), LIN 2.1-compliant transceivers, IEEE-802.3 CRC32 acceleration, and clock supervision with dual LVD stages (interrupt + reset). The external bus interface supports 8-/16-bit NOR Flash and SRAM with address multiplexing and RDY handshake.

FAQ

What is the maximum operating frequency and supported voltage range for CY9AF116NPMC-G-MNE1?

The CY9AF116NPMC-G-MNE1 operates at up to 40 MHz and supports a supply voltage range of 2.7 V to 5.5 V. This wide voltage range accommodates both battery-powered and industrial 5 V rail environments without external regulators, and the 40 MHz clock ensures sufficient processing headroom for real-time motor control loops with sub-10 µs jitter.

Does CY9AF116NPMC-G-MNE1 support hardware LIN communication, and which LIN version is implemented?

Yes, it supports hardware LIN communication compliant with LIN Protocol Specification Rev. 2.1. The integrated LIN controller handles break field generation (13–16 bit), delimiter control (1–4 bit), and automatic checksum calculation, eliminating software overhead and ensuring timing-critical frame transmission within ±1% tolerance at 19.2 kbps baud rate.

How many ADC channels and what resolution does the CY9AF116NPMC-G-MNE1 provide, and what is its conversion time?

It integrates three 12-bit successive approximation ADC units totaling 16 input channels, with a minimum conversion time of 1.0 µs at 5 V supply. The ADC supports scanning mode with 16-step FIFO and priority-based conversion, enabling synchronized sampling of multiple motor phase currents with hardware-triggered start.

Is external memory expansion supported, and what are the interface capabilities?

Yes, the external bus interface supports SRAM and NOR Flash devices with up to 25-bit addressing (128 MB per chip select), 8-/16-bit data width, 8 chip selects, and address/data multiplexing. It also includes RDY signal support for slow memory devices, allowing seamless integration of external program storage or data buffers without glue logic.
