Product details
Overview
CY9AF116NAPMC-GNE2 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.
For engineers reviewing the CY9AF116NAPMC-GNE2 datasheet, CY9AF116NAPMC-GNE2 pinout, CY9AF116NAPMC-GNE2 application, or CY9AF116NAPMC-GNE2 equivalent, key selection criteria include Flash/SRAM size, peripheral count (e.g., 8 serial interfaces, 2 QPRC units), 100-pin LQFP mechanical compatibility, and support for LIN 2.1, hardware flow control (ch.4), and external bus interface (25-bit address, 8 chip selects).
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 scheduling. Its memory subsystem features zero-wait-state Flash access and dual-bus SRAM architecture-SRAM0 connected to I-code/D-code buses for instruction/data caching, SRAM1 on the system bus for DMA-peripheral transfers.
The peripheral set includes an 8-channel DMA controller with independent bus access, multi-function serial interfaces configurable per channel as UART/CSIO/LIN/I²C (4 with 16×9-bit FIFO), and dedicated motor control blocks: 8-channel Base Timers (PWM/PPG/reload/PWC), 2-unit Multi-function Timer with A/D activation compare and waveform generation, and 2-channel QPRC with 16-bit position/revolution counters and programmable edge detection on AIN/BIN/ZIN.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| External Bus Interface | 25-bit address, 8-/16-bit data, 8 chip selects - enables direct connection to external NOR Flash or SRAM for code offloading or data logging. |

FAQ
What is the maximum operating frequency and voltage range for CY9AF116NAPMC-GNE2?
The CY9AF116NAPMC-GNE2 operates at up to 40 MHz across a supply voltage range of 2.7 V to 5.5 V. This wide voltage range supports direct connection to 3.3 V or 5 V industrial power rails without level-shifting, and the 40 MHz clock ensures sufficient processing headroom for real-time motor control loops with <10 µs jitter tolerance.
Does CY9AF116NAPMC-GNE2 support hardware flow control on its UART interfaces?
Yes, hardware flow control (RTS/CTS) is supported exclusively on serial channel 4 (SIN5_0/SOT5_0), as confirmed in the "Multi-function Serial Interface" section of datasheet Rev. *H. Channels 0–3 do not implement CTS/RTS signaling, making ch.4 essential for reliable high-speed UART communication in noisy industrial environments.
How many ADC channels and what resolution does CY9AF116NAPMC-GNE2 provide?
The device integrates three 12-bit successive approximation ADC units supporting up to 16 total input channels. Conversion time is 1.0 µs at 5 V supply, and features include priority-based scanning, built-in FIFO (16-step for scan mode), and A/D activation compare triggers synchronized to timer events-enabling precise current sampling aligned with PWM switching edges.
Is external memory expansion supported, and what interface options are available?
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, and 8 chip selects. It also supports address/data multiplexing and external RDY signal for slow memory devices, enabling boot-from-external-Flash configurations or real-time data buffering in data acquisition systems.
