Infineon Technologies CY9AF112NAPMC-GNE2

Overview

CY9AF112NAPMC-GNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 128 KB on-chip Flash, 16 KB SRAM, and integrated motor control peripherals including 8-channel Base Timers, 3-unit 12-bit ADC (12 channels), and dual watchdog timers (HW + SW). It operates at up to 40 MHz across 2.7–5.5 V and supports UART/CSIO/LIN/I²C serial interfaces - deployed in industrial motor drives and embedded power conversion systems.

For engineers reviewing the CY9AF112NAPMC-GNE2 datasheet, CY9AF112NAPMC-GNE2 pinout, CY9AF112NAPMC-GNE2 application, or CY9AF112NAPMC-GNE2 equivalent, key selection criteria include external bus interface capability (8 CS, 25-bit address), QPRC encoder counter support, CRC accelerator for integrity checking, and SWJ-DP debug interface compliance.

Technical Context

This MCU implements a deterministic real-time control architecture centered on the Arm Cortex-M3 r2p1 core, with tightly coupled memory subsystems (I-code/D-code buses for SRAM0, system bus for SRAM1) and independent DMA controller (8 channels) enabling concurrent peripheral-to-memory transfers without CPU intervention.

Its timing subsystem integrates multiple synchronized timer domains: Base Timers (PWM/PPG/reload modes), Multi-function Timers (input capture, output compare, A/D activation), Quadrature Position/Revolution Counters (2 units), and Dual Timer for precise low-power wake-up - all clocked from configurable sources including main PLL, sub-clock (32.768 kHz), and built-in CR oscillators.

FAQ

What is the maximum operating frequency and voltage range for CY9AF112NAPMC-GNE2?

The CY9AF112NAPMC-GNE2 operates at up to 40 MHz across a supply voltage range of 2.7 V to 5.5 V. Its internal PLL supports clock multiplication from external crystal or built-in CR oscillators, and the 0-wait-state Flash enables full-speed execution without performance throttling. Electrical characteristics are validated per Infineon's recommended operating conditions in Document 002-04672 Rev. *H.

Does CY9AF112NAPMC-GNE2 support hardware flow control on its UART interfaces?

No - hardware flow control (RTS/CTS) is supported only on channel 4 of the multi-function serial interface, and CY9AF112LA/MA/NA/NB variants (including CY9AF112NAPMC-GNE2) explicitly exclude this feature per datasheet footnote on page 2. Software-controlled handshaking or external logic must be used for flow management on other UART channels.

How many A/D converter units and channels does CY9AF112NAPMC-GNE2 integrate?

CY9AF112NAPMC-GNE2 integrates two 12-bit successive approximation A/D converter units, totaling 12 input channels. Each unit supports scanning mode with 16-step FIFO and priority-based conversion with 4-step FIFO. Conversion time is specified at 1.0 μs at 5 V supply, and both units share common reference voltage inputs (AVREFH/AVREFL).

Is the External Bus Interface enabled on CY9AF112NAPMC-GNE2?

Yes - CY9AF112NAPMC-GNE2 supports the External Bus Interface with up to 8 chip selects, 25-bit address bus, and 8-/16-bit data bus width. It interfaces with SRAM and NOR Flash devices and supports address/data multiplexing and external RDY signaling. This capability is confirmed in the Product Lineup table (page 5) and "External Bus Interface" section (page 2) of datasheet 002-04672 Rev. *H.
