Product details
Overview
CY9AFA44MBPMC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with dual-bank flash (240 KB + 16 KB), 32 KB on-chip SRAM (16 KB SRAM0 + 16 KB SRAM1), and integrated LCD controller supporting up to 40 SEG × 8 COM. It operates at up to 40 MHz, supports six low-power modes including Deep Standby RTC, and targets embedded control in industrial HMI and battery-powered instrumentation.
For engineers reviewing the CY9AFA44MBPMC-G-JNE2 datasheet, CY9AFA44MBPMC-G-JNE2 pinout, CY9AFA44MBPMC-G-JNE2 application, or CY9AFA44MBPMC-G-JNE2 equivalent, key selection criteria include dual-operation flash architecture for seamless firmware updates, 24-channel 12-bit ADC with 2.0 μs conversion time, hardware CRC accelerator (CRC16/CRC32), HDMI-CEC/remote receiver support, and 83 GPIOs with port relocation in 100-pin LQFP package.
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 independent I-code/D-code buses for SRAM0 and system bus for SRAM1, enabling concurrent CPU and DMA access without contention.
The peripheral set includes eight base timers (configurable as PWM/PPG/reload/PWC), dual watchdogs (hardware clocked by 100 kHz CR oscillator, active in all low-power modes except Deep Standby Stop), and a dedicated LCDC with internal bias resistors and blinking control-enabling direct drive of segment-based displays without external components.
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 low-latency interrupt handling. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - allows background erase/write in one bank while executing code from the other. |
| SRAM | 32 KB total (16 KB SRAM0 on I/D bus + 16 KB SRAM1 on system bus) - supports parallel CPU and DMA access to separate memory spaces. |
| ADC | 24-channel 12-bit SAR, 2.0 μs conversion @ 2.7–3.6 V - delivers high-speed analog sensing for motor control or sensor fusion. |
| LCDC | 40 SEG × 8 COM, internal bias resistors, VV0–VV4 pins - eliminates need for external voltage dividers in segment LCD applications. |
| Low-Power Modes | Six modes including Deep Standby RTC (RAM retention optional) - extends battery life in always-on monitoring devices. |
| CRC Accelerator | CCITT CRC16 and IEEE-802.3 CRC32 hardware engine - offloads integrity checks from CPU during firmware OTA or sensor data logging. |

Use Value: Dual-stage LVD provides early warning interrupt (LVD1) and hard reset (LVD2) - prevents corrupted flash writes during power collapse. |
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 | Single-bank 256 KB Flash, no integrated LCDC or HDMI-CEC, 72 MHz max clock | Lacks native segment LCD and CEC support - requires external driver ICs and discrete CEC transceiver | Select when higher CPU performance is prioritized over integrated display/remote control peripherals. |
| RA4M1 (R7FA4M1AB3CFM) | ARM Cortex-M4F core, 256 KB Flash, 32 KB SRAM, no LCDC, supports capacitive touch | Offers FPU and touch sensing but omits segment LCD driver and CEC - better suited for GUI-driven interfaces | Select when floating-point math or capacitive touch is required, and LCD is replaced by graphical display. |
Compared with STM32F103VCT6 and RA4M1, CY9AFA44MBPMC-G-JNE2 uniquely integrates segment LCD driving, HDMI-CEC transceiver, and dual-bank flash in a single 100-pin LQFP package - reducing system-level component count and firmware complexity for cost-sensitive embedded HMI and remote-control applications.

FAQ
Does CY9AFA44MBPMC-G-JNE2 support external memory expansion?
No. Unlike earlier CY9AA40NB variants such as CY9AFA41LB, this specific part (FA44MB) does not implement the External Bus Interface. Its memory subsystem relies solely on on-chip dual-bank flash and SRAM, eliminating external NOR/SRAM connections and associated signal integrity concerns.
What debug interfaces are supported?
CY9AFA44MBPMC-G-JNE2 supports Serial Wire JTAG Debug Port (SWJ-DP) only. The Embedded Trace Macrocell (ETM) is not implemented in this variant, as confirmed in the peripheral manual and datasheet revision history - limiting trace capability to SWD-based debugging and basic breakpoint analysis.
Is hardware flow control available on UART channels?
No. Hardware flow control (CTS/RTS) is explicitly excluded from CY9AFA44MBPMC-G-JNE2 per the datasheet footnote on page 2: "CY9AFA41LB, FA42LB and FA44LB do not support Hardware Flow control." Only software-based XON/XOFF or polling-based transmission is supported across all eight serial channels.
Can the internal CR oscillators be used as main clock sources?
Yes. The device supports both built-in high-speed CR (4 MHz) and low-speed CR (100 kHz) oscillators as clock sources. The high-speed CR can feed the Main PLL to generate system clocks up to 40 MHz, enabling full-speed operation without an external crystal - useful in cost-constrained or space-limited designs where crystal placement is impractical.
