Product details
Overview
CY9AFA41NBPQC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with dual-bank flash (240 KB + 16 KB), 32 KB on-chip SRAM (16 KB SRAM0 + 16 KB SRAM1), and integrated LCD controller supporting up to 40×8 segment-combination drive. It operates at up to 40 MHz, supports six low-power modes including Deep Standby RTC, and targets embedded control in industrial HMI and appliance panels.
For engineers reviewing the CY9AFA41NBPQC-G-JNE2 datasheet, CY9AFA41NBPQC-G-JNE2 pinout, CY9AFA41NBPQC-G-JNE2 application, or CY9AFA41NBPQC-G-JNE2 equivalent, key selection criteria include dual-operation flash architecture, 24-channel 12-bit ADC with 2.0 μs conversion time, hardware flow control on UART ch.4, HDMI-CEC transceiver support, and 100-pin LQFP package with 5 V-tolerant I/O 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 integration. Its memory subsystem features independent I-code/D-code and system buses enabling concurrent CPU and DMA access to SRAM0 and SRAM1.
The peripheral set includes an 8-channel DMA controller with 32-bit addressing, dual 12-bit ADC units with FIFO-based scanning and priority conversion, and a programmable LCD controller with internal bias resistors and blinking function - all operating within 1.65–3.6 V supply range (2.2–3.6 V when LCDC active).

FAQ
What is the maximum operating frequency and supported voltage range for CY9AFA41NBPQC-G-JNE2?
The CY9AFA41NBPQC-G-JNE2 operates at up to 40 MHz with a supply voltage range of 1.65 V to 3.6 V. When the LCD controller is active, the minimum supply voltage increases to 2.2 V to ensure stable bias generation and segment drive strength. All DC and AC timing specifications in the datasheet are validated across this full operating range.
Does CY9AFA41NBPQC-G-JNE2 support in-circuit debugging and trace capabilities?
Yes, it supports Serial Wire JTAG Debug Port (SWJ-DP) for full debug access including breakpoints, watchpoints, and register inspection. Unlike earlier FM3 variants, this part also includes Embedded Trace Macrocell (ETM) support for instruction-level trace capture - enabling cycle-accurate profiling and real-time code execution analysis during development.
How does the dual-bank flash architecture improve firmware update reliability?
Dual-bank flash allows one bank (e.g., upper 240 KB) to run active firmware while the other (lower 16 KB work area) is erased and reprogrammed. This enables atomic firmware updates without halting system operation or losing real-time responsiveness - critical for appliances and industrial controls where uninterrupted service is mandatory.
Which pins are 5 V tolerant and how is this verified in the datasheet?
Pins P00–P07, P10–P17, and P20–P27 are specified as 5 V tolerant when configured as general-purpose inputs. This is confirmed in Section 12.3.2 "Pin Characteristics" of datasheet 002-05633 Rev. *D, which lists absolute maximum ratings of –0.3 V to 5.5 V for these I/Os under non-driving conditions - enabling safe interfacing with legacy 5 V logic without level shifters.
