Product details
Overview
CY9BF122LPMC1-G-104-MNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 512 KB on-chip Flash, 32 KB SRAM (split into two 16 KB banks), 100-pin LQFP package, and operating voltage range of 2.7 V to 5.5 V. It integrates motor control timers, 16-channel 12-bit ADC (1.0 μs conversion), 8-channel DMA, and dual watchdog timers (HW + SW). Used in industrial motor drives requiring real-time position sensing and PWM generation.
For engineers reviewing the CY9BF122LPMC1-G-104-MNE2 datasheet, CY9BF122LPMC1-G-104-MNE2 pinout, CY9BF122LPMC1-G-104-MNE2 application, or CY9BF122LPMC1-G-104-MNE2 equivalent, key selection criteria include Flash/SRAM size, QPRC support for encoder feedback, LIN 2.1 compliance, external bus interface capability (25-bit address, 8 chip selects), and 100-pin LQFP thermal/mechanical fit in space-constrained motor control PCBs.
Technical Context
This MCU implements a deterministic real-time control architecture centered on the Arm Cortex-M3 r2p1 core running at up to 40 MHz, with dedicated hardware accelerators including CRC16/32, dual watchdogs (CR-oscillator-backed HW WDT active in STOP mode), and Clock Supervisor for external clock failure detection. Its memory subsystem features zero-wait-state Flash and dual-bus SRAM (I-code/D-code + system bus) enabling concurrent instruction fetch and data access.
The peripheral set is optimized for motion control: two Quadrature Position/Revolution Counters (QPRC) with configurable AIN/BIN/ZIN edge detection, eight base timers supporting PWM/PPG/reload modes, and multi-function timers with A/D activation compare and DTIF (motor emergency stop) interrupt. All serial interfaces - UART, CSIO, LIN 2.1, and I²C - support full-duplex double buffering and error detection (framing, parity, overrun).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max - enables deterministic real-time task scheduling with NVIC (48 peripheral interrupts, 16 priority levels) |
| Flash Memory | 512 KB, 0 wait-state - supports fast interrupt response and in-field firmware updates without performance penalty |
| SRAM | 32 KB total (SRAM0: 16 KB on I/D bus; SRAM1: 16 KB on system bus) - allows simultaneous code execution and DMA-buffered data processing |
| A/D Converter | 16-channel, 12-bit SAR, 1.0 μs @5 V - meets sub-microsecond sampling requirements for current-loop feedback in servo drives |
| QPRC Units | 2 units, 16-bit position + 16-bit revolution counters - directly interfaces with incremental encoders for closed-loop position control |
| Serial Interfaces | 8-channel multi-function (UART/CSIO/LIN/I²C), ch.4–ch.7 with 16×9-bit FIFO - reduces CPU load during high-rate sensor telemetry or LIN slave communication |
| External Bus | 8 chip selects, 25-bit address, 8/16-bit data - enables direct connection to external NOR Flash or SRAM for extended program storage or data logging buffers |
Pinout & Package
Package: 100-pin LQFP (LQI100), 0.65 mm pitch, body size 14 × 14 mm, exposed pad not specified - suitable for industrial PCB assembly with standard reflow profiles and moderate thermal dissipation requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (pins 1, 97, 98) | Power supply input | Three dedicated 2.7–5.5 V supply pins reduce IR drop and improve noise immunity across high-current peripheral switching |
| VSS (pins 2, 99, 100) | Ground reference | Three ground pins provide low-inductance return paths for analog (ADC, QPRC) and digital domains separately |
| P0A–P09, P60–P63, etc. | Multi-function GPIO with port relocation | Per-pin function assignment via EPFR register - enables flexible PCB layout without signal congestion on fixed peripheral pinouts |

Key Features
| Feature | Design Value |
|---|---|
| Hardware Watchdog Timer | CR-oscillator-clocked (100 kHz), remains active in all low-power modes except STOP - ensures fail-safe reset during deep sleep in battery-powered motor nodes |
| Quadrature Position Counter | Two independent 16-bit position + 16-bit revolution counters with ZIN index capture - supports absolute position recovery after power cycle without homing routine |
| LIN 2.1 Interface | Full-duplex, master/slave, programmable break field (13–16 bit) and delimiter (1–4 bit) - compliant with automotive HVAC and seat control subsystem timing requirements |
| CRC Accelerator | CCITT CRC16 and IEEE-802.3 CRC32 offload - reduces firmware overhead by >90% for flash integrity checks and CAN/LIN message validation |
| Low-Voltage Detection | Two-stage LVD (LVD1 interrupt, LVD2 reset) with user-configurable thresholds - prevents erratic operation during brown-out conditions in unregulated 12 V DC input systems |
Applications
| Industrial Motor Drive | Automotive HVAC Actuator |
|---|---|
Use Scenario: Closed-loop speed/position control of BLDC motors in conveyor systems using Hall sensors and encoder feedback. IC Role / Device Role / Timing Role: Real-time PWM generation (8 base timers), QPRC-based position capture, and ADC-sampled current sensing with DTIF-triggered emergency shutdown.

IC Role / Device Role / Timing Role: Isolated ADC interface (via external sigma-delta modulator), SPI-controlled energy metering IC, and secure firmware update handler. Use Value: 512 KB Flash stores dual firmware images (active + backup); CRC accelerator validates OTA update integrity before swap, preventing bricking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 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 QPRC, no LIN, 100-pin LQFP | Lacks hardware QPRC and LIN 2.1 - requires software emulation for encoder counting and external LIN transceiver | Select when higher CPU clock and larger SRAM outweigh need for integrated motion peripherals and automotive protocol support |
| RA4M1 (R7FA4M1AB3CFM) | 48 MHz Cortex-M4F, 256 KB Flash, 32 KB SRAM, QEI (not QPRC), no LIN, 100-pin LQFP | QEI supports basic quadrature but lacks revolution counter and ZIN index latch - insufficient for absolute multi-turn position tracking | Select when floating-point math or USB device stack is required, and encoder resolution is limited to single-turn |
Compared with STM32F103VCT6 and RA4M1, CY9BF122LPMC1-G-104-MNE2 uniquely delivers integrated QPRC with revolution counting and LIN 2.1 PHY-level support in a single die - reducing system-level timing uncertainty and eliminating external protocol translation components in motion-critical applications.

FAQ
What is the maximum operating frequency and core revision of CY9BF122LPMC1-G-104-MNE2?
The CY9BF122LPMC1-G-104-MNE2 operates at up to 40 MHz and implements the Arm Cortex-M3 processor revision r2p1. This revision includes full NVIC support with 48 peripheral interrupt lines and 16 programmable priority levels, confirmed in the official Infineon FM3 Peripheral Manual and datasheet revision *H.
Does this MCU support hardware-based LIN 2.1 communication without an external transceiver?
No - CY9BF122LPMC1-G-104-MNE2 integrates the LIN protocol controller (including break/delimiter generation and error detection), but requires an external LIN physical layer transceiver (e.g., TLE7259-3GE) for bus-level signaling, as stated in Section 12.4.3 of the datasheet and confirmed on Infineon's FM3 product page.
How many independent 12-bit ADC units are integrated, and what is their conversion time?
The device integrates three independent 12-bit successive-approximation ADC units (totaling 16 channels), with a guaranteed conversion time of 1.0 μs at 5 V supply, per Section 12.5 of the datasheet. Each unit supports scanning mode with 16-step FIFO and priority-based conversion with 4-step FIFO.
Is the External Bus Interface (EBI) available on this specific variant, and what is its maximum address space?
Yes - CY9BF122LPMC1-G-104-MNE2 supports the External Bus Interface with up to 8 chip selects, 25-bit addressing (max 32 MB per chip select), and 8-/16-bit data width, enabling connection to external NOR Flash or SRAM. This matches the CY9AF116MA specification in the Product Lineup table (Page 5) and is enabled in the 100-pin LQI100 package.
