Product details
Overview
CY9BF124LQN-G-AVE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with dual-bank flash (256 KB), 32 KB on-chip SRAM, 72 MHz max CPU frequency, and integrated peripherals including UART, I²C, LIN, CSIO, 12-bit ADC (26 channels), dual DAC, RTC, QPRC, and hardware CRC accelerator. It targets low-power embedded motor control and industrial sensing applications requiring real-time responsiveness and code security.
For engineers reviewing the CY9BF124LQN-G-AVE2 datasheet, CY9BF124LQN-G-AVE2 pinout, CY9BF124LQN-G-AVE2 application, or CY9BF124LQN-G-AVE2 equivalent, key selection criteria include dual-operation flash architecture for seamless firmware updates, 5 V-tolerant GPIOs on selected pins, sub-32.768 kHz wake-up capability in Deep Standby RTC mode, and hardware watchdog independence from main clock sources.
Technical Context
The CY9BF124LQN-G-AVE2 implements an Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, coupled with a 24-bit SysTick timer for RTOS scheduling. Its memory subsystem features two independent SRAM banks (SRAM0/SRAM1) connected to I-code/D-code and system buses respectively, enabling concurrent instruction fetch and data access.
Peripheral integration includes eight-channel DMA with 32-bit addressing and burst/block/demand transfer modes, plus a multi-function serial interface supporting four UART/CSIO/LIN/I²C channels with FIFO and hardware flow control (RTS/CTS on ch.4). The QPRC block provides dedicated 16-bit position and revolution counters with configurable AIN/BIN/ZIN edge detection for encoder interfacing.
