Product details
Overview
CY9AFA41NBBGL-GK9E1 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, features hardware flow control on UART ch.4, and targets low-power embedded control in industrial HMI and appliance panels.
For engineers reviewing the CY9AFA41NBBGL-GK9E1 datasheet, CY9AFA41NBBGL-GK9E1 pinout, CY9AFA41NBBGL-GK9E1 application, or CY9AFA41NBBGL-GK9E1 equivalent, key selection criteria include dual-operation flash architecture, 5 V-tolerant GPIO count (up to 83 pins in 100-pin LQFP), RTC with leap-year support, HDMI-CEC transceiver capability, and SWJ-DP debug interface compliance.
Technical Context
This MCU implements an 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 includes dual-bank Flash enabling concurrent read/erase/write operations and two independent SRAM banks (SRAM0 on I/D-code bus, SRAM1 on system bus) for deterministic real-time execution.
The peripheral set integrates a 12-bit ADC with 2.0 μs conversion time across 24 channels, 8-channel DMA with 32-bit addressing, and a programmable LCDC with internal bias resistors and blinking control - all operating within 1.65–3.6 V supply range, with extended 2.2–3.6 V range required when LCDC is active.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, up to 40 MHz - enables deterministic real-time task handling with NVIC and SysTick. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports live firmware updates without halting execution. |
| SRAM | 32 KB total (16 KB SRAM0 + 16 KB SRAM1), separate buses - isolates instruction/data access from system DMA traffic. |
| ADC | 12-bit SAR, 24 channels, 2.0 μs conversion @ 2.7–3.6 V - suitable for fast analog sensing in motor control or power monitoring. |
| LCDC | 40 SEG × 8 COM, internal bias resistors, blinking function - drives segment-based displays without external components. |
| Debug Interface | Serial Wire JTAG Debug Port (SWJ-DP) - provides full debug visibility including breakpoints and trace via standard ARM toolchains. |
| Power Range | 1.65–3.6 V (2.2–3.6 V with LCDC active) - accommodates wide-input industrial supplies 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 pairs per power domain ensure stable core, analog, and LCDC voltage rails. |
| P00–P07, P10–P17, etc. | General-purpose I/O | Up to 83 pins configurable as 5 V-tolerant GPIO with port relocate function for flexible PCB routing. |
| XTAL1 / XTAL2 | Main clock oscillator input | Supports 4–48 MHz crystal or external clock source for precise timing and PLL synchronization. |
| OSC32IN / OSC32OUT | Sub-clock oscillator | Connects to 32.768 kHz crystal for RTC and low-power wake-up timing. |
| SEG0–SEG39, COM0–COM7 | LCD segment/com drive outputs | Direct-drive outputs with internal voltage dividers eliminate need for external bias network. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash architecture | Enables background firmware update: erase/write one bank while executing from the other. |
| HDMI-CEC transceiver | Hardware-accelerated CEC frame generation and ACK reply - reduces CPU load in AV remote control systems. |
| RTC with leap-year logic | Maintains accurate calendar over decades without host software correction or NVRAM backup. |
| Hardware UART flow control (ch.4) | Automatic RTS/CTS handshake prevents data loss during high-speed serial streaming to external modems or sensors. |
| CRC accelerator (CRC16/CRC32) | Offloads integrity checks from CPU - critical for secure OTA firmware validation and sensor data logging. |
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 | Single-bank Flash (256 KB), no integrated LCDC or HDMI-CEC; 72 MHz max clock; 2.0–3.6 V supply. | Lacks native segment LCD drive and CEC protocol engine - requires external driver ICs and software stack. | Select when higher CPU speed and broader ecosystem support outweigh integrated display/CEC needs. |
| RA4M1 (R7FA4M1AB3CFM) | ARM Cortex-M4F core, 48 MHz, 256 KB Flash, 32 KB SRAM; includes capacitive touch IP but no LCDC or CEC. | Superior DSP capability and touch support; no hardware CEC or segment LCD - unsuitable for legacy AV remote integration. | Prefer for new designs requiring floating-point math or capacitive touch, where display is graphical (not segment-based). |
Compared with STM32F103VCT6 and RA4M1, CY9AFA41NBBGL-GK9E1 uniquely delivers integrated segment LCD driving, hardware HDMI-CEC, and dual-bank Flash in a single 100-pin LQFP package - reducing BOM cost and firmware complexity in appliance and industrial panel applications.

FAQ
Is CY9AFA41NBBGL-GK9E1 pin-compatible with other CY9AA40NB series devices?
Yes - it shares the 100-pin LQFP package and pin assignment with CY9AFA41LB and CY9AFA42LB, but differs in feature enablement: CY9AFA41NBBGL-GK9E1 includes hardware flow control on UART ch.4 and full External Bus Interface support, unlike LB variants which omit both.
Does this MCU support external SDRAM via its External Bus Interface?
No - the External Bus Interface supports only SRAM and NOR Flash memory devices, with up to 8 chip selects and 25-bit addressing. SDRAM requires dedicated DRAM controller logic not present in this device.
What is the maximum operating temperature for continuous operation?
The device is rated for industrial temperature range: –40 °C to +85 °C ambient, verified per datasheet Section 12.2. This applies to all operating modes including LCD drive and full peripheral activation under 3.6 V supply.
Can the built-in CRC accelerator compute custom polynomials?
No - the hardware accelerator supports only CCITT CRC16 (0x1021) and IEEE-802.3 CRC32 (0x04C11DB7). Custom polynomial computation must be performed in software using the general-purpose ALU.
