Product details
Overview
CY9AFB44LBPMC1-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 256 KB dual-bank Flash, 32 KB SRAM, USB 2.0 Full-Speed device/host interface, 12-bit ADC (24 channels), and LCD controller (40×8 SEG/COM). It operates at up to 40 MHz, supports six low-power modes, and targets embedded control in industrial HMI and metering systems.
For engineers reviewing the CY9AFB44LBPMC1-G-JNE2 datasheet, CY9AFB44LBPMC1-G-JNE2 pinout, CY9AFB44LBPMC1-G-JNE2 application, or CY9AFB44LBPMC1-G-JNE2 equivalent, key selection criteria include dual-bank Flash for safe firmware updates, USB host/device capability without external PHY, integrated LCDC for segment displays, and 1.65–3.6 V wide supply range with LVD1/LVD2 monitoring.
Technical Context
This MCU implements the ARM Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels. Its memory subsystem includes two independent SRAM banks (SRAM0 on I/D-code bus, SRAM1 on system bus) and dual-operation Flash enabling concurrent read/erase/write across upper (240 KB) and lower (16 KB + 32 KB work area) banks.
The peripheral set integrates USB 2.0 Full-Speed with built-in PLL, HDMI-CEC/remote receiver (2 channels), RTC with leap-year support, 8-channel DMA with burst/block/demand transfer, and multi-function serial interfaces (UART/CSIO/I²C) - four with 16×9-bit FIFOs. Hardware flow control is omitted per datasheet revision *D.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, 40 MHz max - deterministic real-time execution with nested interrupt handling |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - enables over-the-air firmware update without halting operation |
| SRAM | 32 KB total: 16 KB SRAM0 (I/D bus), 16 KB SRAM1 (system bus) - separates instruction/data access to avoid bus contention |
| USB Interface | Full-Speed device/host with built-in PLL - eliminates need for external clock generator or PHY in USB-enabled designs |
| ADC | Two 12-bit SAR units, 24 channels, 2.0 μs conversion @ 2.7–3.6 V - supports high-speed sensor acquisition with scan/priority modes |
| LCDC | 40 SEG × 8 COM, internal bias resistors, blinking function - drives segment-based displays without external driver ICs |
| Power Supply | 1.65–3.6 V (3.0–3.6 V required for USB, 2.2–3.6 V for LCDC) - enables single-supply operation across mixed-peripheral use cases |
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 pins with decoupling requirements per datasheet Section 13.3.2 |
| XTAL, EXTAL | Main clock oscillator inputs | Support 4–48 MHz crystal or external clock source for system timing and USB PLL reference |
| OSC32K, OSC32KOUT | Sub-clock oscillator | Connects to 32.768 kHz crystal for RTC and low-power timer functions |

| SEG0–SEG39, COM0–COM7 | LCD segment/common drivers | Direct drive of multiplexed segment displays; VV0–VV4 provide programmable bias voltage |
| P00–P97 | General-purpose I/O ports | Up to 83 GPIOs with port relocate, pull-up control, and 5 V tolerance on selected pins |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash architecture | Enables background firmware updates: erase/write one bank while executing from the other |
| Integrated USB PLL | Generates precise 48 MHz USB clock from main oscillator - no external crystal or clock buffer needed |
| Hardware-accelerated CRC | Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation - reduces CPU load during communication or storage integrity checks |
| Two-stage LVD | LVD1 triggers interrupt for early warning; LVD2 asserts reset to prevent unreliable operation below safe voltage threshold |
| Deep Standby RTC mode | Maintains RTC timekeeping and optional RAM retention using only sub-clock (32.768 kHz) power - <1 μA typical current draw |
Applications

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 integrated LCDC or HDMI-CEC | Lacks native segment LCD driver and CEC protocol engine - requires external display driver and software CEC stack | Preferred when higher CPU performance and larger SRAM are prioritized over integrated display/remote control features |
| RA4M1 (R7FA4M1AB3CFM) | 48 MHz Cortex-M4F, 256 KB Flash, 32 KB SRAM, no USB host, no LCDC | Includes FPU and TrustZone but omits USB host and segment LCD controller - needs external components for those functions | Chosen for enhanced security and floating-point math where display/remote control are handled externally |
Compared with STM32F103VCT6 and RA4M1, CY9AFB44LBPMC1-G-JNE2 uniquely integrates LCDC, HDMI-CEC/remote receiver, and USB host/device in a single die - reducing BOM count and PCB area for HMI and appliance control applications requiring those peripherals.

FAQ
Does CY9AFB44LBPMC1-G-JNE2 support USB host mode with external device enumeration?
Yes. The MCU implements full USB 2.0 Full-Speed host mode with automatic device connect/disconnect detection, IN/OUT token handshake processing, and up to 256-byte packet support. It enumerates standard class devices like HID keyboards and USB mass storage without external PHY, using only the integrated USB transceiver and PLL.
What is the maximum operating frequency when using the internal CR oscillator?
The built-in high-speed CR oscillator delivers 4 MHz, which can be used directly as system clock or fed into the main PLL for multiplication. When bypassing PLL, maximum CPU frequency is 4 MHz; with PLL enabled and configured for ×10, it reaches 40 MHz - the rated maximum operating frequency per datasheet Section 13.5.4.
Can the LCD controller drive custom segment layouts beyond 40×8?
No. The LCDC hardware is fixed at 40 segment outputs and 8 common outputs. It does not support dynamic reconfiguration beyond this matrix. Custom layouts must fit within 40 SEG × 8 COM; unused segments/comms remain unconnected or grounded per design.
Is hardware flow control available on any UART channel?
No. According to datasheet Rev. *D, hardware flow control (CTS/RTS) is explicitly unsupported on CY9AFB44LBPMC1-G-JNE2 - unlike earlier CY9AB40NB variants. All UART channels rely on software handshaking or application-level buffering for data flow management.
