Product details
Overview
CY9AF316NABGL-GE1 from Spansion (formerly Fujitsu Semiconductor) is a 32-bit ARM Cortex-M3 microcontroller with 512 KB on-chip Flash, 32 KB SRAM (split into two 16 KB banks), and integrated peripherals including USB 2.0 Full-Speed Function/Host, 8-channel DMA, 16-channel 12-bit ADC, and dual QPRC for motor position sensing - deployed in industrial motor control and embedded automation systems.
For engineers reviewing the CY9AF316NABGL-GE1 datasheet, CY9AF316NABGL-GE1 pinout, CY9AF316NABGL-GE1 application, or CY9AF316NABGL-GE1 equivalent, key selection criteria include its 100-pin LQFP package, 40 MHz max CPU frequency, 2.7–5.5 V wide supply range, 5V-tolerant I/O support, and dual-mode USB interface with automatic device connect/disconnect detection.
Technical Context
The CY9AF316NABGL-GE1 implements the ARM Cortex-M3 r2p1 core with Nested Vectored Interrupt Controller (NVIC) supporting 48 peripheral interrupts and 16 priority levels. It integrates a 24-bit SysTick timer for RTOS task scheduling and dual-bus SRAM architecture (I-code/D-code for SRAM0, system bus for SRAM1) to enable concurrent CPU and DMA access.
Its peripheral set targets real-time motion control: two multi-function timers provide PWM, input capture, A/D activation compare, and dead-time insertion; dual QPRC units track quadrature encoder signals with 16-bit position/revolution counters; and the USB controller supports both function (6 endpoints, double-buffered) and host (Full/Low-Speed, 256-byte packet) modes with automatic handshake and wake-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, enabling deterministic interrupt latency and Thumb-2 instruction efficiency for real-time embedded control. |
| Max Clock Frequency | 40 MHz, delivering 33.3 DMIPS performance while maintaining low power consumption in industrial temperature range. |
| Flash Memory | 512 KB zero-wait-state Flash, supporting secure code protection and in-system programming for firmware updates. |
| SRAM | 32 KB total (SRAM0 + SRAM1), split across I-code/D-code and system buses to eliminate memory contention during DMA transfers. |
| ADC | 16-channel 12-bit successive approximation ADC with 1.0 µs conversion time at 5 V, FIFO buffering, and priority/scanning modes. |
| USB Interface | Dual-role USB 2.0 Full-Speed (12 Mbps): Function mode supports 6 endpoints with double buffers; Host mode supports Bulk/Interrupt/Isochronous transfers up to 256-byte packets. |
| I/O Voltage Tolerance | 5V-tolerant GPIO pins (confirmed for MB9AF316MA/NA variants), enabling direct interfacing with legacy 5V logic without level shifters. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407VGT6 | ARM Cortex-M4F core, 168 MHz, 1 MB Flash, no QPRC, single USB OTG FS, 3.3 V only I/O | Higher compute throughput but lacks native quadrature encoder counter; requires external logic or software emulation for motor position tracking | Select when floating-point math or DSP instructions are critical, and encoder interface can be implemented externally or via timer input capture. |
| R7F7010233AFP | Renesas RH850/F1L core, 64 MHz, 512 KB Flash, 64 KB RAM, 16-channel 12-bit ADC, no USB, CAN 2.0B support | Automotive-qualified, includes CAN but no USB; QPRC present but only one unit; no 5V-tolerant I/O | Select for automotive body control modules where CAN integration and AEC-Q100 qualification outweigh USB and 5V I/O requirements. |
