Product details
Overview
CY9AF141NBPMC-G-JNE2 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 integrated peripherals including UART/CSIO/I²C, 24-channel 12-bit ADC (2.0 μs conversion), 8-channel DMA, RTC, HDMI-CEC, and six low-power modes. It targets embedded motor control and industrial HMI applications requiring real-time responsiveness and code security.
For engineers reviewing the CY9AF141NBPMC-G-JNE2 datasheet, CY9AF141NBPMC-G-JNE2 pinout, CY9AF141NBPMC-G-JNE2 application, or CY9AF141NBPMC-G-JNE2 equivalent, key selection criteria include dual-bank Flash for safe firmware updates, 100-pin LQFP package with 83 GPIOs (some 5 V tolerant), 1.65–3.6 V supply range, and hardware flow control on UART ch.4 - all confirmed in Infineon's Rev. *D datasheet (002-05637).
Technical Context
This MCU implements an ARM Cortex-M3 r2p1 core operating up to 40 MHz with NVIC supporting 48 peripheral interrupts and 16 priority levels. Its memory subsystem includes dual-operation Flash (240 KB upper + 16 KB lower bank) enabling concurrent read-while-write, plus two independent SRAM banks (SRAM0 on I/D-code bus, SRAM1 on system bus) for deterministic real-time execution.
The peripheral set is optimized for industrial edge nodes: 8-channel base timers support PWM/PPG/reload/PWC modes; HDMI-CEC transceiver handles header block auto-transmission and ACK generation; CRC accelerator supports CCITT CRC16 and IEEE-802.3 CRC32 for data integrity; and Clock Supervision (CSV) monitors external clock failure/frequency anomaly using internal CR oscillators.

FAQ
What is the maximum operating frequency of the CY9AF141NBPMC-G-JNE2?
The CY9AF141NBPMC-G-JNE2 operates at up to 40 MHz using its ARM Cortex-M3 core. This frequency is achievable with the main clock sourced from either an external 4–48 MHz crystal or the internal high-speed CR oscillator (4 MHz) fed into the Main PLL. The datasheet confirms stable operation at 40 MHz under recommended conditions (VCC = 2.7–3.6 V, TA = –40 to +85 °C).
Does this MCU support hardware debug interfaces?
Yes, the CY9AF141NBPMC-G-JNE2 supports Serial Wire JTAG Debug Port (SWJ-DP) for full debugging, programming, and trace capabilities. It does not include Embedded Trace Macrocell (ETM); ETM is only supported on higher-pin-count variants (CY9AF141LB/MB, etc.). SWJ-DP enables breakpoints, watchpoints, and real-time register inspection via standard ARM debug tools.
How many GPIO pins are available in the 100-pin LQFP package?
The CY9AF141NBPMC-G-JNE2 in 100-pin LQFP provides up to 83 general-purpose I/O pins. These include dedicated pins for external bus, communication interfaces, and analog functions - all configurable as GPIO when not assigned to peripherals. Some pins are 5 V tolerant, as specified in the Pin Description section of the datasheet (Rev. *D, page 16).
Is dual-bank Flash operation supported, and what is its practical benefit?
Yes, dual-bank Flash is fully supported: 240 KB upper bank and 16 KB lower bank allow simultaneous read from one bank while erasing/writing to the other. This enables safe over-the-air (OTA) firmware updates without halting application execution - critical for industrial systems requiring continuous uptime and certified functional safety workflows.
