Product details
Overview
CY9AF144MBPMC-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 - deployed in industrial motor control and smart appliance main control units.
For engineers reviewing the CY9AF144MBPMC-G-JNE2 datasheet, CY9AF144MBPMC-G-JNE2 pinout, CY9AF144MBPMC-G-JNE2 application, or CY9AF144MBPMC-G-JNE2 equivalent, key selection criteria include dual-bank Flash for safe firmware updates, 5 V-tolerant GPIO support, hardware watchdog independence from main clock, and SWJ-DP debug interface compatibility with standard ARM toolchains.
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 scheduling. Its memory subsystem features dual-operation Flash enabling concurrent read-erase-write across upper (240 KB) and lower (16 KB) banks, and split SRAM architecture (SRAM0 on I/D-code bus, SRAM1 on system bus) to reduce core-peripheral contention.
The peripheral set includes eight base timers (configurable as PWM/PPG/reload/PWC), two independent 12-bit ADC units with FIFO-based scanning and priority conversion, and HDMI-CEC transceiver logic with automatic ACK generation and arbitration loss detection - all operating within 1.65–3.6 V supply range and validated for deep standby RTC mode with RAM retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, 40 MHz max - enables deterministic real-time task execution with NVIC interrupt latency under 12 cycles |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports live firmware update without halting application code |
| SRAM | 32 KB total (16 KB SRAM0 + 16 KB SRAM1), split bus mapping - isolates instruction/data access from peripheral DMA transfers |
| ADC | 24-channel 12-bit SAR, 2.0 μs conversion @ 2.7–3.6 V - meets sub-10 μs sampling requirements for closed-loop motor current sensing |
| Low-Power Modes | Six modes including Deep Standby RTC with RAM retention - extends battery life in always-on remote control receivers |
| Debug Interface | Serial Wire JTAG Debug Port (SWJ-DP) only - compatible with CMSIS-DAP, Segger J-Link, and OpenOCD without ETM trace |
| I/O Voltage Tolerance | 5 V tolerant on selected pins - simplifies level-shifting in mixed-voltage industrial I/O subsystems |
Pinout & Package
Package: 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dedicated analog/digital power domains with separate decoupling requirements per datasheet Section 12.3.2 |
| XTAL1/XTAL2 | Main crystal oscillator input/output | Supports 4–48 MHz external crystals; internal load capacitance configurable via register |
| OSC32K1/OSC32K2 | 32.768 kHz RTC crystal terminals | Enables autonomous RTC operation during Stop and Deep Standby RTC modes |
| P00–P07, P10–P17, etc. | Multi-function GPIO ports | Up to 83 pins; port relocate function allows remapping of UART/CSIO/I²C to alternate pins without PCB change |
| RESET | Active-low reset input | Accepts asynchronous deassertion; triggers Power-on Reset, LVD2 reset, or software-initiated reset |
| TMS/TCK/TDO/TDI/SWCLK/SWDIO | SWJ-DP debug interface | 5-pin minimal debug footprint; no TRST or nSRST required for standard programming and halt debugging |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash architecture | Enables background firmware update: erase/write lower bank while executing from upper bank, eliminating system downtime |
| Split SRAM bus mapping | SRAM0 (I/D-code) and SRAM1 (system bus) prevent CPU-DMA bus contention during high-throughput peripheral transfers |
| HDMI-CEC transceiver logic | Hardware-accelerated CEC frame generation (START/EOM/ACK) and automatic ACK reply - offloads 100% of protocol timing-critical tasks from CPU |
| Two-stage LVD monitoring | LVD1 triggers interrupt for graceful shutdown; LVD2 asserts reset to prevent undefined state during brownout - no external supervisor IC needed |
| Port relocate function | Runtime-configurable peripheral pin assignment (e.g., move UART0 from P30/P31 to P50/P51) - increases PCB layout flexibility and reduces BOM variants |
Applications
| Industrial Motor Control | Smart Appliance Main Controller |
|---|---|

| 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 hardware CEC support and true concurrent Flash operations; requires software-managed firmware update | Select when higher CPU speed and larger SRAM outweigh need for CEC or atomic firmware swap |

FAQ
Does CY9AF144MBPMC-G-JNE2 support in-system programming via UART?
No. In-system programming is supported exclusively through the Serial Wire JTAG Debug Port (SWJ-DP). UART is configured as a peripheral interface only and lacks bootloader capability. Firmware updates must be performed using standard ARM debug tools such as pyOCD or Segger Embedded Studio with SWD connection.
What is the maximum operating temperature for this MCU?
The CY9AF144MBPMC-G-JNE2 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed in Section 12.2 (Recommended Operating Conditions) of datasheet 002-05637 Rev. *D, with derating applied above 70 °C for sustained 40 MHz operation.
Is the RTC battery-backed when VCC is removed?
No. The RTC operates from VCC and retains time only during low-power modes (Stop, Deep Standby RTC) while VCC remains within 1.65–3.6 V. It does not include a dedicated VBAT pin or internal capacitor backup; external supercapacitor or coin cell circuitry is required for true battery-backed timekeeping.
Can the 12-bit ADC perform simultaneous sampling across multiple channels?
No. The two 12-bit ADC units operate independently but do not support hardware-triggered simultaneous sampling. Each unit performs sequential conversions per scan sequence; inter-unit synchronization requires software coordination via shared trigger sources like timer overflow events.
