Product details
Overview
CY9AF341LBPMC1-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 256 KB dual-bank Flash, 32 KB SRAM, USB 2.0 Full-Speed device/host interface, 24-channel 12-bit ADC (2.0 µs conversion), and support for six low-power modes including Deep Standby RTC. It targets embedded motor control and industrial sensing systems requiring real-time responsiveness and code security.
For engineers reviewing the CY9AF341LBPMC1-G-JNE2 datasheet, CY9AF341LBPMC1-G-JNE2 pinout, CY9AF341LBPMC1-G-JNE2 application, or CY9AF341LBPMC1-G-JNE2 equivalent, key selection criteria include dual-bank Flash update capability, USB host/device coexistence, hardware CRC acceleration (CRC16/CRC32), and 5V-tolerant GPIO allocation via port relocate function.
Technical Context
This MCU implements an ARM Cortex-M3 r2p1 core operating up to 40 MHz with integrated NVIC (48 peripheral interrupts, 16 priority levels) and SysTick timer. Its memory subsystem includes two independent SRAM banks (SRAM0 on I/D-code bus, SRAM1 on system bus) enabling concurrent CPU and DMA access.
The peripheral set features a multi-function serial interface supporting UART/CSIO/I²C across eight channels, dual 32-/16-bit down counters, HDMI-CEC/remote receiver (2 channels), and a real-time clock with leap-year compensation and configurable alarm interrupts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M3 r2p1, 40 MHz max - enables deterministic real-time task scheduling with hardware divide and Thumb-2 instruction set. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports background firmware updates without halting execution. |
| SRAM | 32 KB total (16 KB SRAM0 + 16 KB SRAM1) - SRAM0 accessible by CPU core for code/data; SRAM1 dedicated to DMA-peripheral transfers. |
| ADC | 24-channel 12-bit SAR, 2.0 µs conversion @ 2.7–3.6 V - meets sub-µs sampling requirements for closed-loop motor current sensing. |
| USB Interface | Full-Speed device/host with built-in PLL, 6 endpoints (EP0–EP5), double-buffered EP1–EP5 - enables simultaneous HID device and mass-storage host operation. |
| Low-Power Modes | Six modes including Deep Standby RTC with RAM retention - extends battery life in remote sensor nodes while preserving timekeeping and critical state. |
| Clock Sources | Five sources: 4–48 MHz main oscillator, 32.768 kHz sub-clock, 4 MHz/100 kHz CR oscillators, Main PLL - allows fail-safe clock supervision and precise RTC calibration. |
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 |
|---|---|---|
| P00–P07 | General-purpose I/O with port relocate | Configurable as UART0 TX/RX, CSIO0, or I²C0 SDA/SCL; 5V-tolerant on select pins per datasheet Table 4-1. |

| P20–P27 | General-purpose I/O with port relocate | Assignable to HDMI-CEC0/1 or Remote Control Receiver inputs; enable IR signal demodulation without external IC. |
| P30–P37 | General-purpose I/O with port relocate | Map to RTC alarm output, Watch Counter interrupt, or LVD reset assertion - critical for autonomous wake-up and fault recovery. |
| VCC / VSS | Power supply / Ground | Separate analog/digital VCC pins (AVCC/DVCC); requires 1.65–3.6 V operation (3.0–3.6 V mandatory when USB active). |
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. |
| Hardware CRC accelerator | Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation from CPU, reducing integrity-check latency in communication stacks. |
| Port relocate function | Allows dynamic assignment of peripheral functions (e.g., UART, I²C, CEC) to any GPIO group - simplifies PCB layout and avoids routing conflicts. |
| Deep Standby RTC mode | Maintains RTC counter and optional RAM retention using only sub-clock (32.768 kHz), drawing <1 µA - ideal for battery-backed timekeeping. |
| HDMI-CEC transmitter/receiver | Handles full CEC protocol stack (header, arbitration, ACK, EOM) in hardware - eliminates need for external CEC transceivers in AV control designs. |

FAQ
Does CY9AF341LBPMC1-G-JNE2 support USB host functionality?
Yes, it integrates a full-featured USB 2.0 Full/Low-speed host controller supporting bulk, interrupt, and isochronous transfers, automatic device detection, and up to 256-byte packet length. The built-in USB PLL generates the required 48 MHz clock from the main oscillator.
What is the maximum ADC sampling rate and resolution?
The device contains two 12-bit successive approximation ADC units supporting up to 24 input channels. Each conversion completes in 2.0 µs at 2.7–3.6 V supply, enabling sustained sampling rates up to 500 kSPS per unit under optimal timing conditions.
Can the Flash memory be updated while the application runs?
Yes, its dual-bank Flash architecture allows one bank (e.g., upper 240 KB) to execute code while the other (lower 16 KB work area) is erased and reprogrammed - enabling seamless firmware updates without system interruption or external memory.
Is hardware debug supported, and what interface is used?
It supports Serial Wire JTAG Debug Port (SWJ-DP) compliant with ARM CoreSight standards. This enables full-cycle debugging, flash programming, and real-time trace via standard tools like Segger J-Link or ST-Link v2, without requiring additional debug circuitry on the target board.
