Product details
Overview
CY9AFA41LBPMC1-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 256 KB dual-bank Flash, 32 KB SRAM (16 KB SRAM0 + 16 KB SRAM1), 40 MHz max CPU frequency, and integrated LCD controller supporting up to 40 SEG × 8 COM. It targets low-power embedded control in industrial HMI and consumer remote interfaces.
For engineers reviewing the CY9AFA41LBPMC1-G-JNE2 datasheet, CY9AFA41LBPMC1-G-JNE2 pinout, CY9AFA41LBPMC1-G-JNE2 application, or CY9AFA41LBPMC1-G-JNE2 equivalent, key selection criteria include dual-bank Flash for seamless firmware updates, 24-channel 12-bit ADC with 2.0 µs conversion time, HDMI-CEC/remote receiver support, RTC with leap-year handling, and six low-power modes including Deep Standby RTC with RAM retention.
Technical Context
This MCU implements the ARM Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus a 24-bit SysTick timer for OS task scheduling. Its memory subsystem features dual-operation Flash enabling concurrent read-erase-write across upper (240 KB) and lower (16 KB) banks, and two independent SRAM blocks (SRAM0 on I/D-code bus, SRAM1 on system bus).
The peripheral set includes an 8-channel DMA controller with 32-bit addressing, multi-function serial interfaces (UART/CSIO/I²C) across 8 channels, and a dedicated HDMI-CEC transceiver with automatic header block transmission and ACK generation. Hardware flow control is excluded per datasheet footnote for this variant.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash architecture | Enables background firmware update: erase/write one bank while executing from the other |
| Independent SRAM0/SRAM1 buses | Prevents CPU-memory contention during DMA transfers to peripherals like ADC or UART |
| Hardware CRC accelerator (CRC16/CRC32) | Offloads integrity checks from CPU, reducing latency in secure boot or communication stack validation |
| Two watchdog timers (HW/SW) | Hardware watchdog runs on 100 kHz CR oscillator - remains active in all low-power modes except Deep Standby Stop |
| Port relocation function | Allows dynamic assignment of UART, I²C, or timer outputs to alternate pins - improves board routing flexibility |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103VCT6 | ARM Cortex-M3, 72 MHz, 256 KB Flash, no integrated LCDC or HDMI-CEC | Requires external LCD driver and discrete CEC transceiver for equivalent functionality | Select when higher CPU performance is critical and display/CEC are handled externally |
| RA4M1 (R7FA4M1AB3CFM) | ARM Cortex-M4F, 48 MHz, 256 KB Flash, 32 KB SRAM, no HDMI-CEC, includes USB FS | Lacks native CEC support but adds USB device interface for PC-connected diagnostics | Select when USB connectivity outweighs CEC requirement and floating-point math is needed |
Compared with STM32F103VCT6 and RA4M1, CY9AFA41LBPMC1-G-JNE2 uniquely integrates LCD controller and HDMI-CEC transceiver in a single chip, reducing BOM count and PCB area for cost-sensitive consumer remote and HMI applications - at the trade-off of lower maximum clock speed and absence of USB.

FAQ
Does CY9AFA41LBPMC1-G-JNE2 support external bus interface?
No. According to the official datasheet (Rev. *D, page 2), CY9AFA41LB, FA42LB, and FA44LB variants explicitly do not support External Bus Interface. This omission reduces pin count and simplifies PCB design for applications that rely solely on on-chip memory and serial peripherals.
What is the maximum operating voltage for the LCD controller?
The LCD controller requires VCC = 2.2 V to 3.6 V, as specified in the "Recommended Operating Conditions" section (page 72). Operation below 2.2 V disables LCDC functionality, though core logic remains active at 1.65 V minimum.
Is hardware flow control available on UART channels?
No. Datasheet footnote on page 2 confirms that CY9AFA41LB, FA42LB, and FA44LB do not support hardware flow control (CTS/RTS), even though channel 4 is designated for this feature in other FM3 series members.
How many GPIO pins are 5 V tolerant?
Specific pins are 5 V tolerant - confirmed in the "Pin Description" section (page 15) and "I/O Circuit Type" table (page 41). These include PA0–PA7, PB0–PB7, and selected LCD segment pins; exact assignment must be verified against the pin function table for this package variant.
