Product details
Overview
CY9AF315MAPMC-G-MNE2 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), USB 2.0 Full-Speed device/host interface, and integrated motor control peripherals including 8-channel Base Timers, 2-unit QPRC, and A/D converter with 16 channels and 1.0 μs conversion time at 5 V. It targets cost-sensitive industrial motor control and embedded automation systems.
For engineers reviewing the CY9AF315MAPMC-G-MNE2 datasheet, CY9AF315MAPMC-G-MNE2 pinout, CY9AF315MAPMC-G-MNE2 application, or CY9AF315MAPMC-G-MNE2 equivalent, key selection criteria include USB dual-role capability, 100-pin LQFP package with 83 GPIOs (including 5V-tolerant pins), dual-bank SRAM architecture for real-time task isolation, and hardware CRC accelerator supporting CCITT CRC16 and IEEE-802.3 CRC32.
Technical Context
The CY9AF315MAPMC-G-MNE2 implements an Arm Cortex-M3 r2p1 core operating up to 40 MHz with NVIC supporting 48 peripheral interrupts across 16 priority levels and a 24-bit SysTick timer. Its memory subsystem includes zero-wait-state Flash and two independent SRAM banks-SRAM0 connected to I-code/D-code buses for instruction/data caching, and SRAM1 on the system bus for DMA-accessible buffers.
Peripheral integration centers on deterministic real-time control: dual-mode USB (device/host), eight-channel multi-function serial interface (UART/CSIO/LIN/I²C), three 12-bit ADC units with FIFO-based scanning and priority conversion, and dedicated motor timing blocks including PPG, PWM, dead-time insertion, and QPRC with configurable A/B/Z input edge detection.
Key Specifications

FAQ
What debug interfaces does CY9AF315MAPMC-G-MNE2 support?
The device supports Serial Wire JTAG Debug Port (SWJ-DP) only - it does not include Embedded Trace Macrocell (ETM). SWJ-DP enables full breakpoint, watchpoint, and memory access capabilities via standard Arm CoreSight tools, sufficient for firmware development and real-time debugging of motor control algorithms without trace streaming overhead.
Does CY9AF315MAPMC-G-MNE2 support 5V-tolerant I/O pins?
Yes - specific pins (PA0–PA7, PB0–PB7, PC0–PC7, PD0–PD7, PE0–PE7, PF0–PF7, PG0–PG7, PH0–PH7, PJ0–PJ7, PK0–PK7) are 5V-tolerant when configured as inputs, enabling direct connection to legacy 5V industrial sensors and logic without level-shifting circuitry.
Can the USB interface operate in both device and host modes simultaneously?
No - USB operates in either device or host mode, selected at runtime via software configuration of the USB controller registers. Mode switching requires reinitialization and cannot occur mid-transfer, but both roles are fully supported within the same silicon die.
What is the maximum operating temperature range for CY9AF315MAPMC-G-MNE2?
The device is rated for industrial temperature range: –40 °C to +85 °C ambient, validated per JEDEC JESD22-A108. This rating applies to the full 100-pin LQFP package variant and covers all specified electrical characteristics including Flash write/erase endurance and SRAM retention.
