Product details
Overview
CY9AF144LBPMC1-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 256 KB dual-bank Flash, 32 KB on-chip SRAM (16 KB SRAM0 + 16 KB SRAM1), 40 MHz max CPU frequency, and integrated peripherals including UART/CSIO/I²C (up to 8 serial channels), 24-channel 12-bit ADC (2.0 μs conversion), RTC, HDMI-CEC, and six low-power modes. It targets embedded motor control and industrial HMI applications requiring deterministic real-time response and code security.
For engineers reviewing the CY9AF144LBPMC1-G-JNE2 datasheet, CY9AF144LBPMC1-G-JNE2 pinout, CY9AF144LBPMC1-G-JNE2 application, or CY9AF144LBPMC1-G-JNE2 equivalent, key selection criteria include dual-bank Flash for safe firmware updates, 5 V-tolerant GPIO support, hardware CRC acceleration (CRC16/CRC32), and SWJ-DP debug interface without ETM - critical for certified industrial firmware development and field-upgrade reliability.
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 (240 KB upper + 16 KB lower bank) enabling concurrent read-while-write, and two independent SRAM banks (SRAM0 on I/D-code bus, SRAM1 on system bus) for deterministic data access.
The peripheral set includes a DMA controller with 8 channels supporting byte/half-word/word transfers up to 4 GB address space, base timers configurable as PWM/PPG/reload/PWC, and a dedicated HDMI-CEC module with automatic header/ACK/EOM generation and repeat-code detection for remote control systems - all operating within 1.65–3.6 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, 40 MHz max - enables deterministic real-time task execution with low interrupt latency. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports safe over-the-air firmware updates without halting execution. |
| SRAM | 32 KB total (16 KB SRAM0 + 16 KB SRAM1), separate buses - isolates instruction/data traffic from system DMA for predictable timing. |
| ADC | 24-channel 12-bit SAR, 2.0 μs conversion @ 2.7–3.6 V - meets sub-μs sampling requirements for closed-loop motor current sensing. |
| Serial Interfaces | Up to 8 channels: UART/CSIO/I²C; ch.4 supports hardware RTS/CTS flow control - enables robust multi-protocol communication in noisy industrial environments. |
| Power Modes | Six modes including Deep Standby RTC/Stop with RAM retention - extends battery life in always-on remote sensors while preserving context. |
| Clock Sources | Five sources: 4–48 MHz main oscillator, 32.768 kHz sub-clock, 4 MHz/100 kHz CR oscillators, PLL - allows precise clock supervision and fail-safe timekeeping. |
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 supply domains with decoupling requirements per datasheet Section 12.3.2. |
| XTAL / EXTAL | Main clock oscillator input/output | Drives 4–48 MHz crystal; requires external 12–22 pF load capacitors for stable startup. |
| OSC32K / OSC32KOUT | 32.768 kHz RTC crystal interface | Supports low-power RTC operation during Stop/Deep Standby modes with ±20 ppm accuracy. |
| PA0–PA15, PB0–PB15, etc. | Multi-function GPIO | Up to 83 pins; port relocate function allows dynamic peripheral mapping; some pins 5 V tolerant - simplifies legacy interface integration. |
| SWDIO / SWCLK | Serial Wire Debug interface | Enables non-intrusive debugging and flash programming via SWJ-DP; no ETM support per Rev. *D datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash memory | Enables background firmware update: erase/write one bank while executing from the other - eliminates system downtime during field upgrades. |
| Hardware CRC accelerator | Offloads CCITT CRC16 and IEEE-802.3 CRC32 calculations from CPU - reduces integrity check latency for CAN/UART frame validation by >90%. |
| HDMI-CEC transceiver | Integrated header/ACK/EOM generation and arbitration loss detection - eliminates external CEC PHY for TV/AVR remote control subsystems. |
| Two watchdog timers | Independent hardware (CR-oscillator-clocked) and software watchdogs - ensures fail-safe recovery even during deep sleep or clock failure scenarios. |
| Low-voltage detection (LVD) | Two-stage monitoring (LVD1 interrupt, LVD2 reset) at programmable thresholds - prevents corrupted Flash writes or SRAM data loss during brown-out conditions. |
Applications
| Industrial Motor Control | Smart Home HMI Panel |

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 hardware CEC and safe firmware update capability; requires external PHY for IR/CEC | Select when higher CPU throughput is needed and CEC is handled externally. |
| RP2040 | Dual-core ARM Cortex-M0+, 2 MB Flash, 264 KB SRAM, no RTC or hardware CRC accelerator | No built-in RTC or LVD; relies on software CRC; lacks industrial-grade voltage range (1.8–3.3 V only) | Select for cost-sensitive consumer devices where deep sleep current and CEC are not required. |
Compared with STM32F103VCT6 and RP2040, CY9AF144LBPMC1-G-JNE2 uniquely combines dual-bank Flash for fail-safe updates, integrated HDMI-CEC, and industrial 1.65–3.6 V operation - making it optimal for certified embedded systems where firmware integrity and protocol offload are mandatory.

FAQ
Does CY9AF144LBPMC1-G-JNE2 support JTAG debugging?
No. This device supports Serial Wire JTAG Debug Port (SWJ-DP) only, as confirmed in Rev. *D datasheet page 5. JTAG TDI/TDO pins are not implemented; debug access requires SWDIO and SWCLK signals with standard ARM SWD protocol. The absence of ETM limits trace depth but maintains full breakpoint and memory inspection capability.
What is the maximum operating temperature range for this MCU?
CY9AF144LBPMC1-G-JNE2 is rated for industrial temperature range: –40 °C to +85 °C, verified per Absolute Maximum Ratings (Section 12.1) and Recommended Operating Conditions (Section 12.2) in datasheet Rev. *D. Thermal derating begins above 85 °C ambient, and operation outside this range may cause Flash write failure or SRAM retention loss.
Can the external bus interface be enabled on this part?
No. CY9AF144LBPMC1-G-JNE2 explicitly excludes External Bus Interface support, as stated in the datasheet footnote on page 2: "CY9AF141LB, F142LB and F144LB do not support External Bus Interface." Pin functions for address/data multiplexing are unassigned, and related registers are read-only or reserved.
Is hardware flow control available on all UART channels?
No. Hardware flow control (RTS/CTS) is supported only on UART channel 4, as documented in the "Hardware Flow control" footnote on page 2 of Rev. *D datasheet. Channels 0–3 lack dedicated CTS/RTS pins and associated control logic; software-based XON/XOFF must be used for those interfaces.
