Product details

Overview

CY9AF112NAPF-G-JNE1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 256 KB on-chip Flash, 32 KB SRAM (16 KB SRAM0 + 16 KB SRAM1), 100-pin LQFP package, and integrated motor control peripherals including 8-channel Base Timers, 3-unit 12-bit ADC (16-channel total), and QPRC for encoder position sensing - deployed in industrial motor drives and HVAC blower control systems.

For engineers reviewing the CY9AF112NAPF-G-JNE1 datasheet, CY9AF112NAPF-G-JNE1 pinout, CY9AF112NAPF-G-JNE1 application, or CY9AF112NAPF-G-JNE1 equivalent, key selection criteria include its 40 MHz max CPU frequency, dual watchdog (HW + SW), external bus interface (25-bit address, 8-/16-bit data, 8 chip selects), CRC accelerator (CCITT CRC16/IEEE-802.3 CRC32), and support for LIN 2.1, UART, I²C, and CSIO across up to 8 serial channels.

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 RTOS scheduling. Its memory subsystem features zero-wait-state Flash execution and dual-bus SRAM architecture - SRAM0 connected to I-code/D-code buses for instruction/data caching, SRAM1 on system bus for DMA-accessible buffers.

The peripheral set is optimized for real-time motor control: Base Timers support PWM/PPG/PWC/reload modes; Multi-function Timers provide input capture, output compare, A/D activation, and waveform generation; QPRC units accept quadrature A/B/Z inputs with configurable edge detection and dual 16-bit counters; and the 12-bit ADC achieves 1.0 μs conversion at 5 V with FIFO-based scanning and priority-level arbitration.

FAQ

What is the maximum operating frequency and voltage range for CY9AF112NAPF-G-JNE1?

The CY9AF112NAPF-G-JNE1 operates at up to 40 MHz and supports a supply voltage range of 2.7 V to 5.5 V. This wide voltage tolerance allows direct integration into industrial 3.3 V and 5 V systems without level-shifting, and the 40 MHz clock enables sub-microsecond interrupt latency for fast motor control loop closure.

Does CY9AF112NAPF-G-JNE1 support hardware quadrature decoding?

Yes - it integrates two Quadrature Position/Revolution Counter (QPRC) units, each accepting AIN/BIN/ZIN inputs with configurable edge detection, 16-bit position/revolution counters, and dual compare registers. This eliminates the need for external counter ICs or CPU-intensive software quadrature decoding in servo and BLDC applications.

Is external memory expansion supported, and what interfaces are available?

Yes - the device includes a full External Bus Interface supporting SRAM and NOR Flash with up to 25-bit addressing (128 MB per chip select), 8-/16-bit data width, 8 chip selects, and external RDY handshake. This enables expansion beyond on-chip 256 KB Flash and 32 KB SRAM for firmware overlays, data logging, or FPGA co-processing.

What debug and trace capabilities does CY9AF112NAPF-G-JNE1 provide?

It features Serial Wire JTAG Debug Port (SWJ-DP) and Embedded Trace Macrocell (ETM) support, enabling real-time instruction tracing, breakpoint setting, and memory inspection. The TRACED0–TRACED3 and TRACECLK pins on Port 0 provide four-bit trace clock/data output, essential for optimizing motor control loop timing and diagnosing race conditions in multi-interrupt environments.
