Product details
Overview
CY9AF144MBPMC1-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with dual-bank flash (256 KB), 32 KB SRAM, 24-channel 12-bit ADC (2.0 µs conversion), and integrated HDMI-CEC/remote control receiver - designed for low-power embedded control in industrial HMI, smart appliance UI, and remote-sensor gateways.
For engineers reviewing the CY9AF144MBPMC1-G-JNE2 datasheet, CY9AF144MBPMC1-G-JNE2 pinout, CY9AF144MBPMC1-G-JNE2 application, or CY9AF144MBPMC1-G-JNE2 equivalent, key selection criteria include dual-operation flash architecture, 1.65–3.6 V supply range, 83 GPIOs (some 5 V tolerant), RTC with leap-year support, and SWJ-DP debug interface without ETM.
Technical Context
This MCU implements the ARM Cortex-M3 r2p1 core at up to 40 MHz with NVIC supporting 48 peripheral interrupts and 16 priority levels. It integrates dual-bank Flash (240 KB upper + 16 KB lower + 32 KB work area) enabling concurrent read/erase/write operations - critical for firmware-over-the-air (FOTA) updates without system halt.
The peripheral set includes eight base timers (PWM/PPG/reload/PWC), two watchdogs (hardware clocked by 100 kHz CR oscillator), CRC accelerator for CCITT CRC16 and IEEE-802.3 CRC32, and HDMI-CEC transceiver with automatic ACK, START/EOM generation, and arbitration-loss detection - all operating within six low-power modes including Deep Standby RTC with RAM retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, up to 40 MHz - enables deterministic real-time task scheduling with 24-bit SysTick timer for OS integration. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower + 32 KB work area), 0-wait-state read - supports background firmware update and secure code protection. |
| SRAM | 32 KB total: 16 KB SRAM0 (I/D-code bus), 16 KB SRAM1 (system bus) - enables cache-like separation for instruction/data coherency. |
| ADC | 24-channel 12-bit SAR ADC, 2.0 µs conversion @ 2.7–3.6 V - delivers high-speed sensor sampling for motor control or environmental monitoring. |
| Low-Power Modes | Six modes including Deep Standby RTC with optional RAM retention - extends battery life in always-on remote controllers and IoT edge nodes. |
| HDMI-CEC | Integrated transmitter/receiver with automatic ACK, START/EOM, and arbitration-loss interrupt - eliminates external CEC PHY for TV accessory control. |
| Debug Interface | Serial Wire JTAG Debug Port (SWJ-DP) only - provides full debug access without Embedded Trace Macrocell (ETM) overhead. |
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 / Ground | Dual 1.65–3.6 V core I/O supply with dedicated analog/digital ground separation for noise-sensitive ADC operation. |
| XTAL / EXTAL | Main clock input/output | 4–48 MHz crystal oscillator interface - enables precise timing for UART baud rate generation and real-time control loops. |
| RTCXTAL / RTCXTALO | Sub-clock input/output | 32.768 kHz crystal connection - powers RTC and Watch Counter during Stop/Deep Standby modes for calendar timekeeping. |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/O | Up to 83 GPIOs with per-pin pull-up control, direct level read, and port relocate function - allows flexible PCB layout and peripheral remapping without hardware change. |
| CEC_IN / CEC_OUT | HDMI-CEC signal interface | Dedicated bidirectional CEC pins with internal line driver/receiver - supports direct connection to 100 Ω CEC bus without external transceiver. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash memory | Enables simultaneous firmware execution and update - critical for fail-safe OTA upgrades in field-deployed devices. |
| 8-channel DMA controller | Independent bus master with byte/half-word/word transfer - offloads CPU from high-bandwidth data movement (e.g., ADC-to-SRAM streaming). |
| 2-stage Low-Voltage Detector (LVD) | LVD1 triggers interrupt for graceful shutdown; LVD2 asserts reset - prevents corrupted flash writes during brown-out conditions. |
| Clock Supervision (CSV) | Monitors external clock frequency and stoppage using internal CR oscillators - ensures system reliability in mission-critical timing applications. |
| 5 V-tolerant GPIOs | Selected pins tolerate 5 V inputs while powered at 3.3 V - simplifies interface with legacy 5 V peripherals without level shifters. |

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 HDMI-CEC, no dual-bank flash, 12-bit ADC @ 1 µs | Lacks native CEC support; requires external transceiver for TV control; higher performance but larger power envelope | Select when higher CPU throughput and larger SRAM are needed, and CEC is not required. |

FAQ
Does CY9AF144MBPMC1-G-JNE2 support external memory expansion?
No. Unlike earlier CY9A140NB series variants (e.g., CY9AF141LB), this part omits the External Bus Interface. It relies solely on on-chip 256 KB dual-bank Flash and 32 KB SRAM for program and data storage - simplifying PCB design and reducing BOM count for self-contained applications.
What debug interfaces does CY9AF144MBPMC1-G-JNE2 support?
It supports Serial Wire JTAG Debug Port (SWJ-DP) only. The Embedded Trace Macrocell (ETM) is not implemented in this variant - confirmed in the datasheet revision *D. Debugging is fully functional for breakpoints, register inspection, and flash programming, but instruction trace is unavailable.
Is hardware flow control supported on UART channels?
No. Hardware flow control (CTS/RTS) is explicitly excluded from CY9AF144MBPMC1-G-JNE2 per the datasheet - unlike some earlier FM3 parts. Only UART channel 4 supports this feature in compatible variants; here, all eight serial channels operate in standard UART/CSIO/I2C mode without RTS/CTS signaling.
How is the 41-bit Unique ID accessed and used?
The 41-bit factory-programmed unique ID is stored in a dedicated ROM region and readable via the System Control Block (SCB) registers. It is commonly used for secure boot key derivation, device authentication in cloud-linked appliances, and anti-cloning measures - with no user-write capability and guaranteed uniqueness across the FM3 product family.
