Product details
Overview
CY9AFA41MBBGL-GK9E1 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 256 KB dual-bank Flash (240 KB upper + 16 KB lower), 32 KB on-chip SRAM (16 KB SRAM0 + 16 KB SRAM1), and operation up to 40 MHz. It integrates LCD controller (40 SEG × 8 COM), 24-channel 12-bit ADC (2.0 μs conversion), 8-channel DMA, and supports six low-power modes including Deep Standby RTC/Stop - deployed in industrial HMI panels requiring integrated display control and sensor interfacing.
For engineers reviewing the CY9AFA41MBBGL-GK9E1 datasheet, CY9AFA41MBBGL-GK9E1 pinout, CY9AFA41MBBGL-GK9E1 application, or CY9AFA41MBBGL-GK9E1 equivalent, key selection criteria include dual-bank Flash execution-in-place capability, 5 V-tolerant GPIO allocation via port relocate function, HDMI-CEC/remote receiver support, and sub-3.6 V operation with LVD1/LVD2 voltage monitoring.
Technical Context
This MCU implements ARM Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus 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 32-/16-bit down counters, and multi-function serial interfaces (UART/CSIO/I²C) with hardware flow control on channel 4 - all clocked from five selectable sources including 4–48 MHz main oscillator, 32.768 kHz sub-clock, and PLL-derived clocks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, 40 MHz max - enables deterministic real-time task handling with NVIC interrupt latency under 12 cycles. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports background erase/write while executing from opposite bank. |
| SRAM | 32 KB total: 16 KB SRAM0 (I/D bus), 16 KB SRAM1 (system bus) - isolates instruction/data traffic from DMA transfers. |
| ADC | 24-channel 12-bit SAR, 2.0 μs conversion @ 2.7–3.6 V - meets <5 μs sampling requirement for motor current sensing loops. |
| Low-Power Modes | Six modes including Deep Standby RTC/Stop with RAM retention option - achieves <1 μA RTC-only current at 32.768 kHz sub-clock. |
| Operating Voltage | 1.65–3.6 V (2.2–3.6 V when LCDC active) - compatible with single Li-ion or dual-cell alkaline supply rails. |
| Package | 100-pin LQFP (14 × 14 mm, 0.5 mm pitch) - provides 83 fast GPIOs with port relocate and 5 V tolerance on designated pins. |
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 domains (core/analog) with dedicated VSS pairs - reduces switching noise coupling into ADC reference path. |
| XTAL1/XTAL2 | Main crystal oscillator input/output | Supports 4–48 MHz external crystal - enables precise timing for UART baud generation and PWM carrier frequency stability. |
| OSC32IN/OSC32OUT | 32.768 kHz sub-clock crystal interface | Drives RTC and Watch Counter independently - maintains timekeeping during deep sleep with <1 μA quiescent current. |
| SEG0–SEG39, COM0–COM7 | Segment and common outputs for LCD driver | Direct drive of 40×8 segment LCD without external bias circuitry - reduces BOM count in cost-sensitive HMI designs. |
| P00–P57, P60–P67, P70–P77 | Multi-function GPIO with port relocate | 83 total pins; 5 V tolerant on P0x/P1x/P2x - allows direct interface to legacy 5 V logic or sensors without level shifters. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash architecture | Enables Over-The-Air (OTA) firmware updates without halting real-time control tasks - critical for field-deployed industrial gateways. |
| Port relocate function | Allows dynamic remapping of UART/CSIO/I²C peripherals to alternate GPIO sets - simplifies PCB layout and avoids signal congestion on high-density boards. |
| HDMI-CEC + remote control receiver | Integrated dual-channel CEC transceiver with automatic ACK/START/EOM generation - eliminates need for discrete CEC PHY in smart TV accessory controllers. |
| CRC accelerator (CRC16/CRC32) | Offloads integrity checking from CPU during firmware update packet validation or sensor data logging - reduces CPU load by >90% vs software CRC. |
| Hardware watchdog (CR-clocked) | Remains active in Sleep/Timer/RTC/Stop modes - ensures fail-safe recovery even during extended low-power intervals in battery-powered IoT nodes. |

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 LCD controller or HDMI-CEC | Lacks native segment LCD drive and CEC PHY - requires external components for HMI or remote control functions | Select 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 dual-bank Flash or CEC, includes TrustZone | Offers FPU and security extensions but omits LCD controller and CEC - better suited for secure connectivity than embedded display control | Select when cryptographic acceleration or secure boot is required, and display/remote functionality is handled externally |
Compared with STM32F103VCT6 and RA4M1, CY9AFA41MBBGL-GK9E1 delivers unique integration of LCD driver, HDMI-CEC transceiver, and dual-bank Flash - reducing component count and firmware complexity in cost-sensitive, display-centric embedded controllers where 40 MHz performance suffices.

FAQ
Does CY9AFA41MBBGL-GK9E1 support JTAG debugging?
Yes, it supports Serial Wire JTAG Debug Port (SWJ-DP) compliant with ARM CoreSight standards. The device does not include Embedded Trace Macrocell (ETM); only SWJ-DP is implemented for debug and programming access. No external debug adapter license is required beyond standard ARM-compliant tools like Segger J-Link or ST-Link v2 clones.
What is the maximum operating temperature range for this MCU?
The CY9AFA41MBBGL-GK9E1 is rated for industrial temperature range: –40 °C to +85 °C. This is confirmed in Section 12.2 (Recommended Operating Conditions) of datasheet 002-05633 Rev. *D. Thermal derating is not required within this range when PCB layout follows recommended copper pour and thermal vias per Infineon's FM3 layout guidelines.
Can the internal CR oscillators be used as system clock sources?
Yes - both built-in high-speed CR (4 MHz) and low-speed CR (100 kHz) oscillators are selectable as clock sources. The high-speed CR can feed the Main PLL to generate up to 48 MHz system clock; the low-speed CR drives the Watchdog Timer and remains active in most low-power modes except Deep Standby Stop/RTC.
Is external bus interface available on this part number?
No - CY9AFA41MBBGL-GK9E1 does not support External Bus Interface. This is explicitly stated in the datasheet: "CY9AFA41LB, FA42LB and FA44LB do not support External Bus Interface." The 'MB' suffix variant shares the same peripheral disablement as the LB series, confirmed in Package and Pin Assignment tables (pages 7–8).
