Product details
Overview
CY9BF124KQN-G-AVE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 256 KB dual-bank Flash, 32 KB SRAM (16 KB SRAM0 + 16 KB SRAM1), and operation up to 72 MHz. It integrates UART, I²C, LIN, CSIO, 12-bit ADC (26 channels, 0.8 µs conversion), dual 10-bit DAC, RTC, QPRC, and eight-channel DMA - deployed in motor control, industrial sensing, and embedded HMI systems.
For engineers reviewing the CY9BF124KQN-G-AVE2 datasheet, CY9BF124KQN-G-AVE2 pinout, CY9BF124KQN-G-AVE2 application, or CY9BF124KQN-G-AVE2 equivalent, key selection criteria include dual-bank Flash for safe firmware updates, 5 V-tolerant GPIOs on selected pins, sub-32 kHz RTC clock support, hardware CRC acceleration (CRC16/32), and six low-power modes including Deep Standby RTC with RAM retention.
Technical Context
The CY9BF124KQN-G-AVE2 implements an 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 independent I-code/D-code buses for SRAM0 and a system bus for SRAM1, enabling concurrent instruction fetch and data access.
Peripheral integration includes a multi-function serial interface with eight channels (four with 16×9-bit FIFO), LIN 2.1-compliant transceivers, and a quadrature position/revolution counter with configurable AIN/BIN/ZIN edge detection, 16-bit position/revolution counters, and two compare registers - all optimized for real-time motion control feedback loops.

FAQ
Does CY9BF124KQN-G-AVE2 support in-system programming via SWD?
Yes. The device features a Serial Wire JTAG Debug Port (SWJ-DP) compliant with ARM CoreSight standards, enabling full debug, flash programming, and boundary scan through standard SWD interfaces. No external bootloader is required - factory-programmed ROM boot loader supports UART-based firmware recovery if user code corrupts flash.
What is the maximum operating temperature range for CY9BF124KQN-G-AVE2?
The CY9BF124KQN-G-AVE2 is rated for industrial temperature range: –40 °C to +85 °C ambient. All electrical characteristics in the datasheet (Document No. 002-05655 Rev. *K) are guaranteed across this range, including Flash endurance (100 k erase/write cycles) and ADC accuracy (±2 LSB INL).
Can the dual-bank Flash be used for A/B firmware swapping?
Yes. The dual-bank architecture allows one bank (e.g., upper 240 KB) to run active firmware while the other (lower 16 KB work area) stores updated code. Bank switching is controlled via Flash control registers, and the hardware supports atomic bank swap upon reset - enabling zero-downtime field updates.
Is the RTC functional in Deep Standby Stop mode?
No. In Deep Standby Stop mode, the RTC is disabled. However, Deep Standby RTC mode retains RTC operation with calendar/timekeeping active while drawing <1 µA - with optional SRAM retention. This mode uses the 32.768 kHz sub-clock and maintains RTC registers, alarms, and calendar counters autonomously.
