Product details
Overview
CY9AF141NBPQC-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 operation up to 40 MHz. It integrates UART/CSIO/I²C interfaces, 24-channel 12-bit ADC (2.0 µs conversion), 8-channel DMA, RTC, HDMI-CEC, and six low-power modes - designed for embedded motor control and industrial sensor nodes.
For engineers reviewing the CY9AF141NBPQC-G-JNE2 datasheet, CY9AF141NBPQC-G-JNE2 pinout, CY9AF141NBPQC-G-JNE2 application, or CY9AF141NBPQC-G-JNE2 equivalent, key selection criteria include dual-bank Flash execution while programming, 5 V-tolerant GPIO support on select pins, hardware flow control on UART ch.4, and sub-3.6 V operation with LVD1/LVD2 voltage monitoring.
Technical Context
The device 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 system bus for SRAM1, enabling concurrent instruction fetch and data access.
Peripheral integration includes a dedicated baud rate generator per serial channel, priority-scanning ADC with 16-step FIFO, and dual watchdogs - one clocked by the 100 kHz CR oscillator for deep-sleep supervision. Clock supervision uses built-in CR oscillators to detect external clock stoppage or frequency anomaly via CSV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, 40 MHz max - enables deterministic real-time task handling with NVIC interrupt nesting |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports background reprogramming without halting code execution |
| SRAM | 32 KB total (16 KB SRAM0 on I/D bus + 16 KB SRAM1 on system bus) - decouples core instruction/data traffic from peripheral DMA transfers |
| ADC | 24-channel 12-bit SAR, 2.0 µs conversion @ 2.7–3.6 V - meets <5 µs sampling requirements for closed-loop motor current sensing |
| Low-Power Modes | Six modes including Deep Standby RTC/Stop with RAM retention options - extends battery life in remote sensor endpoints |
| Operating Voltage | 1.65 V to 3.6 V - compatible with single-cell Li-ion, 3.3 V logic rails, and energy-harvesting power supplies |
| Package | 100-pin LQFP (PQC), 0.5 mm pitch - provides 83 fast GPIOs with port relocation and select 5 V-tolerant inputs |
Pinout & Package
Package: 100-pin LQFP (PQC), 14 mm × 14 mm, 0.5 mm pitch, exposed pad (EP), RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual VCC/VSS pairs per side ensure stable core/peripheral rail decoupling; EP connects to VSS for thermal conduction |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/O | 83 total GPIOs; port relocate function allows dynamic assignment of UART/ADC/timer functions to physical pins |
| XTAL1 / XTAL2 | Main clock oscillator input | Accepts 4–48 MHz crystal or external clock; drives PLL for high-speed CPU/peripheral operation |
| OSC32KIN / OSC32KOUT | Sub-clock oscillator | Connects to 32.768 kHz crystal for RTC and Watch Counter timing in all low-power modes except Deep Standby Stop |
| INITX | External reset input | Active-low asynchronous reset pin; triggers Power-on Reset sequence and releases internal reset latches |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash architecture | Enables Over-The-Air (OTA) firmware updates with zero downtime: execute from upper bank while writing to lower bank |
| Hardware UART flow control (ch.4) | CTS/RTS handshaking prevents buffer overflow in high-throughput serial communication with modems or gateways |
| HDMI-CEC transceiver | Integrated CEC protocol engine handles header block transmission, arbitration loss detection, and automatic ACK reply - eliminates external CEC PHY |
| Two-stage LVD (LVD1/LVD2) | LVD1 generates interrupt for graceful shutdown; LVD2 asserts reset to prevent undefined state during brownout below 1.65 V |
| CRC accelerator (CRC16/CRC32) | Offloads integrity checking from CPU: processes received CAN/UART frames or stored firmware images at full bus speed |
Applications
| Industrial Motor Control | Smart Home Sensor Hub |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit ARM Cortex-M3 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103VCT6 | 72 MHz Cortex-M3, 256 KB Flash, 48 KB SRAM, no dual-bank Flash or HDMI-CEC | Lacks integrated CEC and runtime Flash reprogramming capability; requires external transceiver for AV control | Select when higher CPU throughput is needed and CEC is not required |
| RP2040 | Dual-core ARM Cortex-M0+, 2 MB Flash, 264 KB SRAM, no hardware CEC or analog peripherals | No built-in ADC, no CEC, no hardware flow control - relies on software UART and external ADC | Select for cost-sensitive consumer IoT where dual-core simplicity outweighs analog integration |
Compared with STM32F103VCT6 and RP2040, CY9AF141NBPQC-G-JNE2 uniquely combines dual-bank Flash for OTA updates, hardware CEC, and 24-channel 12-bit ADC in a single 100-pin LQFP - reducing system-level component count for industrial and AV control designs.

FAQ
Does CY9AF141NBPQC-G-JNE2 support debug via SWD or JTAG?
Yes - it features Serial Wire JTAG Debug Port (SWJ-DP) compliant with ARM CoreSight standards. Debug access is enabled through SWDIO/SWCLK pins; JTAG TDI/TDO/TMS/TCK are multiplexed but not supported on this variant per the FM3 Peripheral Manual TYPE6 classification.
What is the maximum operating temperature range for this MCU?
The CY9AF141NBPQC-G-JNE2 is rated for industrial temperature range: –40 °C to +85 °C. This is confirmed in Section 12.2 "Recommended Operating Conditions" of datasheet 002-05637 Rev. *D, specifying ambient temperature limits under VCC = 1.65–3.6 V.
Can the 32 KB SRAM be used as a unified memory space?
No - SRAM is physically split: SRAM0 (16 KB) connects to Cortex-M3 I-code and D-code buses for instruction/data cache coherency, while SRAM1 (16 KB) sits on the system bus for DMA-peripheral transfers. Software must explicitly allocate buffers to each region based on access pattern.
Is hardware flow control available on all UART channels?
No - hardware flow control (CTS/RTS) is implemented only on UART channel 4, as documented in the "Hardware Flow control" footnote on page 2 of the datasheet. Channels 0–3 support software XON/XOFF only; no dedicated RTS/CTS pins are assigned to those channels.
