Product details
Overview
CY9AF144NBPMC-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 24-channel 12-bit ADC, 8-channel DMA, UART/CSIO/I²C serial interfaces, RTC, HDMI-CEC, and six low-power modes. It operates at up to 40 MHz across 1.65–3.6 V and targets embedded motor control and industrial HMI applications.
For engineers reviewing the CY9AF144NBPMC-G-JNE2 datasheet, CY9AF144NBPMC-G-JNE2 pinout, CY9AF144NBPMC-G-JNE2 application, or CY9AF144NBPMC-G-JNE2 equivalent, key selection criteria include dual-bank Flash for safe firmware updates, hardware flow control support (not present in F141LB/F142LB/F144LB variants), 5 V-tolerant I/O capability on selected pins, and SWJ-DP debug interface compatibility.
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 operations across upper (240 KB) and lower (16 KB) banks, and split SRAM architecture (SRAM0 on I/D-code bus, SRAM1 on system bus) for deterministic real-time access.
The peripheral set includes eight base timers configurable as PWM/PPG/reload/PWC units, two watchdogs (hardware clocked by 100 kHz CR oscillator, active in all low-power modes except Deep Standby), and CRC accelerator supporting CCITT CRC16 and IEEE-802.3 CRC32 for data integrity in communication and storage paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, up to 40 MHz - enables deterministic real-time execution with Thumb-2 instruction set and hardware divide. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports background firmware update without halting application code. |
| SRAM | 32 KB total (16 KB SRAM0 + 16 KB SRAM1), split bus mapping - isolates instruction/data traffic from system peripherals for predictable latency. |
| A/D Converter | 24-channel 12-bit SAR ADC, 2.0 μs conversion @ 2.7–3.6 V - meets sub-μs sampling requirements for closed-loop motor current sensing. |
| Low-Power Modes | Six modes: Sleep, Timer, RTC, Stop, Deep Standby RTC, Deep Standby Stop - enables <1 μA retention current with RAM state preservation. |
| Debug Interface | Serial Wire JTAG Debug Port (SWJ-DP) - provides non-intrusive real-time debugging and flash programming via standard ARM toolchains. |
| Supply Voltage | 1.65 V to 3.6 V - compatible with single-cell Li-ion, 3.3 V logic rails, and battery-backed operation. |
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 | Dedicated analog/digital power pins enable noise isolation for ADC and PLL operation. |

| RTC_XTAL / RTC_EXTAL | Sub-clock input/output | Connects 32.768 kHz crystal for autonomous RTC operation during deep sleep modes. |
| P00–P07, P10–P17, etc. | General-purpose I/O | Up to 83 GPIOs with per-pin pull-up control, port relocation, and select 5 V-tolerant pins for mixed-voltage interfacing. |
| SWDIO / SWCLK | Debug interface signals | Two-pin Serial Wire Debug interface replaces JTAG pins, reducing debug footprint while maintaining full trace capability. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash memory | Enables over-the-air firmware updates with zero downtime: one bank executes while the other is erased/written. |
| Hardware watchdog (CR-clocked) | Remains active in all low-power states except Deep Standby RTC/Stop - ensures fail-safe recovery even during ultra-low-power operation. |
| HDMI-CEC transceiver | Integrated header block auto-generation, ACK reply, and arbitration loss detection - eliminates external CEC PHY for TV/AVR remote control systems. |
| CRC accelerator (CRC16/CRC32) | Offloads integrity checking from CPU during UART/Flash data transfers - reduces interrupt latency and improves throughput in safety-critical protocols. |
| Port relocation function | Allows dynamic remapping of peripheral functions (UART, I²C, timers) to alternate GPIOs - simplifies PCB layout and enables pin-compatible variant migration. |

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 |
|---|---|---|---|
| CY9AF142NBPMC-G-JNE2 | Same package and core, but lacks HDMI-CEC and Remote Control Receiver peripherals; identical Flash/SRAM and low-power modes. | Not suitable for HDMI ecosystem integration; appropriate for cost-sensitive motor control where CEC is unused. | Select when CEC functionality is unnecessary and BOM cost reduction is prioritized over feature headroom. |
| STM32F103VCT6 | ARM Cortex-M3 at 72 MHz, 256 KB Flash, 48 KB SRAM; no dual-bank Flash, no HDMI-CEC, different peripheral set (USB, SDIO). | Better suited for USB-host applications; lacks native CEC and sub-μA deep sleep with RTC retention. | Choose when USB connectivity or higher CPU clock is required, accepting trade-offs in firmware update safety and ultra-low-power CEC support. |
Compared with CY9AF144NBPMC-G-JNE2, CY9AF142NBPMC-G-JNE2 removes CEC but retains identical power/performance specs, while STM32F103VCT6 offers higher clock speed and USB but sacrifices dual-bank Flash safety and CEC integration - making CY9AF144NBPMC-G-JNE2 optimal for HDMI-adjacent embedded controllers requiring robust field updates and ultra-low-power operation.

FAQ
Does CY9AF144NBPMC-G-JNE2 support hardware flow control on UART?
No. Hardware flow control (CTS/RTS) is explicitly excluded from CY9AF144NBPMC-G-JNE2 per the official FM3 Peripheral Manual - it is only supported on CY9AF141LB, F142LB, and F144LB variants. This part relies on software handshaking or FIFO-based buffering for UART data management.
What is the maximum operating frequency of the ARM Cortex-M3 core in this device?
The CY9AF144NBPMC-G-JNE2 operates at up to 40 MHz, as confirmed in the "Features" section of datasheet 002-05637 Rev. *D. This frequency is achievable across the full 1.65–3.6 V supply range and ambient temperature of –40°C to +85°C.
Is external bus interface supported on this part?
No. The CY9AF144NBPMC-G-JNE2 does not support the External Bus Interface, consistent with the CY9AF141LB, F142LB, and F144LB variants as stated in the datasheet. All memory expansion must be handled via SPI, I²C, or internal Flash/SRAM resources.
How many independent SRAM blocks does this MCU contain, and how are they mapped?
This MCU contains two independent SRAM blocks: SRAM0 (16 KB) connected to the Cortex-M3 I-code and D-code buses for instruction and data caching, and SRAM1 (16 KB) connected to the system bus for peripheral DMA and general-purpose data storage - enabling concurrent CPU and DMA access without bus contention.
