Product details
Overview
CY9AFA44NBBGL-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 40×8 segments. It operates at up to 40 MHz, supports six low-power modes including Deep Standby RTC, and features hardware CRC acceleration for CCITT CRC16 and IEEE-802.3 CRC32 - deployed in industrial HMI panels requiring local display control and secure firmware integrity checks.
For engineers reviewing the CY9AFA44NBBGL-GK9E1 datasheet, CY9AFA44NBBGL-GK9E1 pinout, CY9AFA44NBBGL-GK9E1 application, or CY9AFA44NBBGL-GK9E1 equivalent, key selection criteria include dual-operation flash architecture, 5 V-tolerant GPIO count (up to 83 pins in 100-pin LQFP), HDMI-CEC/remote receiver support, and absence of external bus interface and hardware flow control on UART ch.4.
Technical Context
This MCU implements an ARM Cortex-M3 r2p1 core with tightly coupled I-code/D-code buses feeding SRAM0 and a system bus connecting SRAM1, enabling concurrent CPU and DMA access. Its memory subsystem includes dual-bank flash allowing background erase/write while executing from the other bank - critical for field firmware updates without system interruption.
The peripheral set is optimized for embedded HMI: LCDC drives segmented LCDs directly with internal bias resistors and blinking control; HDMI-CEC logic handles header block transmission, arbitration loss detection, and automatic ACK reply; and two-stage LVD (LVD1 interrupt, LVD2 reset) plus Clock Supervisor (CSV) provide robust power and clock monitoring in unattended equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, up to 40 MHz - deterministic real-time execution with NVIC supporting 48 peripheral interrupts and 16 priority levels. |
| Flash Memory | 256 KB total (240 KB upper bank + 16 KB lower bank), dual-operation capable - enables seamless firmware update via bank-swapping without halting operation. |
| SRAM | 32 KB total (16 KB SRAM0 on I/D bus + 16 KB SRAM1 on system bus) - allows simultaneous CPU instruction fetch and DMA data transfer. |
| Low-Power Modes | Six modes including Deep Standby RTC with RAM retention option - extends battery life in always-on remote control receivers and smart meters. |
| LCD Controller | Supports 40 SEG × 8 COM with internal bias resistors and VV0–VV4 pins - eliminates external LCD bias circuitry in cost-sensitive industrial displays. |
| HDMI-CEC | Transmitter with auto-header generation and receiver with ACK reply & line error detection - enables interoperable consumer electronics control without external protocol ICs. |
| CRC Accelerator | Hardware CCITT CRC16 and IEEE-802.3 CRC32 - offloads integrity checking from CPU during OTA firmware download or sensor data logging. |
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 VCC domains (core/analog) with dedicated VSS pairs - ensures noise isolation for ADC and LCDC operation. |
| P00–P07, P10–P17, etc. | General-purpose I/O | Up to 83 GPIOs; port relocate function allows flexible peripheral mapping; some pins 5 V tolerant - simplifies interface to legacy 5 V logic or sensors. |
| SEG0–SEG39, COM0–COM7 | LCD segment/common drivers | Dedicated output pins with internal charge pump and bias resistor network - drives passive LCDs directly without external components. |
| CEC_IN / CEC_OUT | HDMI-CEC signal interface | Open-drain outputs with internal pull-up - meets HDMI-CEC electrical specification (±0.5 V tolerance, 1.5 kΩ pull-up target). |
| XTAL1 / XTAL2 | Main crystal oscillator input/output | Supports 4–48 MHz crystals - enables precise timing for UART baud rates and real-time control loops. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank flash memory | Enables over-the-air firmware updates with zero downtime: one bank executes while the other is erased/written. |
| Integrated LCD controller | Drives 40×8 segment LCDs using only VV0–VV4 bias pins and SEG/COM outputs - reduces BOM by eliminating external LCD driver ICs. |
| HDMI-CEC transceiver | Handles full CEC protocol stack in hardware: automatic header transmission, arbitration loss detection, and ACK reply - removes need for external CEC PHY or software protocol stack. |
| Two-stage low-voltage detection | LVD1 triggers interrupt for graceful shutdown; LVD2 asserts reset to prevent corrupted memory writes - enhances reliability in brown-out conditions. |
| Port relocation | Allows assignment of UART, I²C, or CSIO functions to multiple GPIO groups - improves PCB layout flexibility and avoids routing congestion. |

FAQ
Does CY9AFA44NBBGL-GK9E1 support external memory expansion?
No. Unlike earlier CY9AA40NB variants (e.g., CY9AFA41LB), this part number explicitly omits the External Bus Interface per the datasheet - it supports only on-chip flash and SRAM. Designers must rely on internal memory or serial interfaces (SPI/I²C) for external storage.
What LCD voltage ranges does the built-in bias generator support?
The LCDC provides five bias voltage outputs (VV4 to VV0) derived from VCC, supporting standard 1/3-bias and 1/4-bias LCD configurations. With VCC = 2.2–3.6 V (required when LCDC is active), it delivers appropriate segment/common voltage differentials for 3.3 V and 2.5 V LCD glass without external resistive dividers.
Is hardware flow control available on any UART channel?
No. The datasheet confirms that CY9AFA44NBBGL-GK9E1 - like CY9AFA41LB and CY9AFA42LB - does not support hardware flow control (CTS/RTS) on UART channel 4 or any other channel. Flow control must be implemented in software using XON/XOFF or application-level handshaking.
How is the 41-bit Unique ID accessed in firmware?
The 41-bit device-unique identifier is stored in a read-only register at address 0x000C0000 (within the system control block region). It is accessible via standard ARM memory-mapped load instructions without special unlock sequences, and remains valid across all power modes including Deep Standby Stop.
