Product details
Overview
CY9AFA42NBBGL-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 peripherals including LCD controller (40×8), 24-channel 12-bit ADC (2.0 μs conversion), 8-channel DMA, and HDMI-CEC/remote receiver - deployed in industrial HMI panels requiring low-power operation and real-time control.
For engineers reviewing the CY9AFA42NBBGL-GK9E1 datasheet, CY9AFA42NBBGL-GK9E1 pinout, CY9AFA42NBBGL-GK9E1 application, or CY9AFA42NBBGL-GK9E1 equivalent, key selection criteria include dual-bank Flash execution capability, 100-pin LQFP package with 83 GPIOs (some 5 V tolerant), RTC with leap-year support, six low-power modes (including Deep Standby RTC), and hardware flow control on UART ch.4.
Technical Context
This MCU implements an ARM Cortex-M3 r2p1 core operating up to 40 MHz with NVIC supporting 48 peripheral interrupts and 16 priority levels. It integrates dual-operation Flash enabling concurrent read-while-write across upper (240 KB) and lower (16 KB + 32 KB work area) banks, plus two independent SRAM blocks (SRAM0 on I/D bus, SRAM1 on system bus).
The peripheral set includes a 40-segment × 8-common LCD controller with internal bias resistors and blinking function; eight base timers configurable as PWM, PPG, reload, or PWC; and dual watchdogs - one hardware-based (CR oscillator clocked, active in Sleep/Timer/RTC modes) and one software-controlled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M3 r2p1, up to 40 MHz - enables deterministic real-time task scheduling with 24-bit SysTick timer for OS integration. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports firmware updates without halting execution via bank-swapping. |
| SRAM | 32 KB total: 16 KB SRAM0 (I/D bus), 16 KB SRAM1 (system bus) - isolates instruction/data access from peripheral DMA traffic. |
| 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. |
| Low-Power Modes | Six modes including Deep Standby RTC (RAM retention optional) - extends battery life in always-on remote control receivers and smart meters. |
| Operating Voltage | 1.65–3.6 V (2.2–3.6 V when LCDC active) - enables direct interface with Li-ion batteries and wide-input industrial power rails. |
| Package | 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) - provides 83 GPIOs with port relocation and selective 5 V tolerance for legacy signal interfacing. |
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 | Dual VCC pins (VCC1/VCC2) and multiple VSS reduce noise coupling; supports separate analog/digital domain decoupling. |
| XTAL1/XTAL2 | Main crystal oscillator input/output | Accepts 4–48 MHz external crystal - primary clock source for PLL and high-speed peripheral operation. |
| OSC32IN/OSC32OUT | 32.768 kHz sub-clock input/output | Drives RTC and Watch Counter independently - maintains timekeeping during deep sleep with ultra-low current draw. |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/O with multiplexing | 83 total GPIOs; port relocate function allows dynamic assignment of UART/I²C/LCDC functions to alternate pins - simplifies PCB layout revision. |
| VLCD, VV4–VV0 | LCD bias voltage generation | Internal resistor ladder generates LCD segment/com drive voltages - eliminates external bias components for 40×8 segment displays. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash memory | Enables seamless firmware updates: erase/write one bank while executing from the other - critical for field-upgradable industrial controllers. |
| HDMI-CEC transmitter/receiver | Hardware-accelerated CEC protocol handling (header auto-transmit, ACK reply, arbitration loss detection) - reduces CPU load in AV equipment remote control stacks. |
| Hardware UART flow control (ch.4) | CTS/RTS handshaking implemented in silicon - prevents data loss at high baud rates in noisy industrial serial links. |
| CRC accelerator (CRC16/CRC32) | Offloads integrity checking from CPU using CCITT and IEEE-802.3 polynomials - accelerates firmware OTA verification and communication packet validation. |
| Two independent watchdogs | Hardware watchdog (CR-clocked) remains active in Sleep/Timer/RTC modes; software watchdog offers flexible timeout configuration - layered safety for fail-safe embedded systems. |

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 built-in LCD controller or HDMI-CEC; 72 MHz max clock; 80 GPIOs in 100-pin LQFP. | Lacks native CEC/IR receiver and segment LCD driver - requires external components for HMI display and AV remote functions. | Select when higher CPU performance is prioritized over integrated HMI peripherals and ultra-low-power CEC operation. |
| RA4M1 (R7FA4M1AB3CFM) | ARM Cortex-M4F core, 48 MHz, 256 KB Flash, 32 KB SRAM; includes capacitive touch IP and USB FS - no CEC or LCD controller. | No hardware CEC engine or LCD bias generation; targets touch-based UIs rather than segment displays or AV control stacks. | Choose for USB-connected gateways needing floating-point math or capacitive touch, not for CEC/IR-optimized remote receivers. |
Compared with STM32F103VCT6 and RA4M1, CY9AFA42NBBGL-GK9E1 uniquely integrates HDMI-CEC hardware, 40×8 LCD driving capability, and dual-bank Flash - making it optimal for cost-sensitive, low-power AV control and industrial segment-display applications where peripheral integration reduces BOM count and board area.

FAQ
Does CY9AFA42NBBGL-GK9E1 support hardware flow control on all UART channels?
No. Hardware flow control (CTS/RTS) is supported only on UART channel 4, as confirmed in the FM3 Peripheral Manual and datasheet Rev. *D. Channels 0–3 lack dedicated CTS/RTS pins and associated control logic. This design enables robust serial communication in noisy environments for critical telemetry links while conserving pin count and silicon area on other channels.
What is the maximum segment count supported by the integrated LCD controller?
The LCDC supports up to 40 segments and 8 commons, configurable in 8-COM or 4-COM mode. In 4-COM mode, it drives up to 160 segments (40 × 4). The controller includes internal dividing resistors and dedicated bias pins (VV4–VV0), eliminating need for external voltage dividers in standard segment LCD applications.
Can the dual-bank Flash be used for secure firmware updates without external memory?
Yes. The 240 KB upper bank and 16 KB lower bank allow one bank to run active firmware while the other receives and validates new code. Combined with the CRC accelerator (CCITT CRC16/IEEE CRC32), this enables fully self-contained, atomic firmware updates with integrity checking - no external Flash or RAM required.
Is the 41-bit Unique ID accessible via standard debug interface?
Yes. The factory-programmed 41-bit unique identifier is readable via the Serial Wire Debug (SWD) interface using standard CMSIS-DAP or J-Link commands, and is also accessible at runtime through dedicated memory-mapped registers (FM3 system control block). It requires no special unlock sequence.
