Product details
Overview
CY9AF115NAPF-G-JNE1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 384 KB on-chip Flash, 32 KB SRAM (split into two 16 KB banks), 16-channel 12-bit ADC, 8-channel DMA, and support for UART/CSIO/LIN/I²C serial interfaces across up to 8 channels. It operates at up to 40 MHz, supports 2.7–5.5 V supply, and targets motor control and industrial embedded systems requiring real-time peripheral integration.
For engineers reviewing the CY9AF115NAPF-G-JNE1 datasheet, CY9AF115NAPF-G-JNE1 pinout, CY9AF115NAPF-G-JNE1 application, or CY9AF115NAPF-G-JNE1 equivalent, key selection criteria include its 100-pin LQFP package, dual SRAM bus architecture, hardware LIN 2.1 support, external bus interface (25-bit address, 8-/16-bit data), and QPRC-based encoder position tracking capability.
Technical Context
This MCU implements the 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 (I/D-code and system buses) enabling concurrent CPU and DMA access without contention.
The peripheral set includes three independent 12-bit ADC units (16 total channels, 1.0 μs conversion @5 V), eight base timers configurable as PWM/PPG/reload counters, two QPRC units for quadrature encoder interfacing, and a CRC accelerator supporting CCITT CRC16 and IEEE-802.3 CRC32 for data integrity in communication and storage paths.
