Infineon Technologies MB9AF314LAPMC-G-JNE2

Overview

MB9AF314LAPMC-G-JNE2 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, dual QPRC units, and A/D converters. It operates at up to 40 MHz, supports 2.7–5.5 V supply, and targets embedded motor control and industrial automation systems.

For engineers reviewing the MB9AF314LAPMC-G-JNE2 datasheet, MB9AF314LAPMC-G-JNE2 pinout, MB9AF314LAPMC-G-JNE2 application, or MB9AF314LAPMC-G-JNE2 equivalent, key selection criteria include USB dual-role capability, 16-bit PWM/PPG timer count, dual QPRC for encoder feedback, 12-bit ADC conversion time (1.0 μs @ 5 V), and external bus interface omission in this variant.

Technical Context

The MB9AF314LAPMC-G-JNE2 implements an Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus a 24-bit SysTick timer. Its memory subsystem features zero-wait-state Flash and dual-bus-connected SRAM banks-SRAM0 on I-code/D-code buses, SRAM1 on system bus-enabling concurrent CPU and DMA access.

Peripherals include eight multi-function serial channels (UART/CSIO/LIN/I²C), two multi-function timers with input capture, output compare, and A/D activation, and a dedicated CRC accelerator supporting CCITT CRC16 and IEEE-802.3 CRC32. Clock supervision uses built-in CR oscillators to monitor external clock failure or frequency anomaly.

FAQ

Does MB9AF314LAPMC-G-JNE2 support USB host mode?

Yes, it supports USB 2.0 Full-Speed and Low-Speed host mode with automatic device connect/disconnect detection, IN/OUT token handshake, and up to 256-byte packet length. Host mode requires USBVCC supplied at 3.0–3.6 V and proper external termination.

What is the maximum operating frequency and clock source flexibility?

The device operates up to 40 MHz using main clock (4–48 MHz crystal or external oscillator), sub-clock (32.768 kHz), or built-in CR oscillators (4 MHz high-speed, 100 kHz low-speed). Main PLL enables frequency multiplication for USB and system clocks.

Is external bus interface available on this variant?

No, MB9AF314LAPMC-G-JNE2 does not include External Bus Interface functionality. That feature is present in MB9AF315MA/NA variants but intentionally omitted here to reduce pin count and cost for self-contained applications.

How many A/D converter units are integrated and what is their resolution?

It integrates two independent 12-bit successive-approximation A/D converters. Each supports scanning and priority conversion modes, with FIFO storage (16-step scan, 4-step priority) and 1.0 μs conversion time at 5 V supply.
