Product details
Overview
CY9BF122KPMC-GNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 256 KB dual-bank Flash, 32 KB on-chip SRAM (16 KB SRAM0 + 16 KB SRAM1), and operation up to 72 MHz. It integrates UART, CSIO, I²C, LIN, 26-channel 12-bit ADC (0.8 µs conversion), dual 10-bit DAC, eight base timers, RTC, QPRC, and six low-power modes - deployed in motor control, industrial sensing, and embedded HMI systems.
For engineers reviewing the CY9BF122KPMC-GNE2 datasheet, CY9BF122KPMC-GNE2 pinout, CY9BF122KPMC-GNE2 application, or CY9BF122KPMC-GNE2 equivalent, key selection criteria include dual-bank Flash for safe firmware updates, 5 V-tolerant GPIOs (up to 65 pins), hardware CRC accelerator (CRC16/CRC32), SWJ-DP debug interface, and integrated clock supervisor with LVD1/LVD2 voltage monitoring.
Technical Context
The CY9BF122KPMC-GNE2 implements the Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus a 24-bit SysTick timer for RTOS scheduling. Its memory subsystem separates instruction (I-code) and data (D-code) paths for SRAM0 while SRAM1 connects via system bus - enabling concurrent CPU and DMA access without contention.
Peripheral integration includes eight-channel DMA with 32-bit addressing, multi-function serial interfaces configurable per channel as UART/CSIO/LIN/I²C, and dedicated motor-control blocks: PWM/PPG timers, dead-time insertion, A/D activation triggers, and DTIF emergency stop interrupt - all synchronized to a common clock domain with programmable prescalers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 72 MHz max - enables deterministic real-time execution with Thumb-2 instruction set and hardware divide. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports simultaneous erase/write/read for robust OTA firmware updates. |
| SRAM | 32 KB total: 16 KB SRAM0 (I/D bus), 16 KB SRAM1 (system bus) - isolates core fetches from DMA transfers to prevent bus stalls. |
| ADC | 26-channel 12-bit SAR, 0.8 µs conversion @ 5 V - delivers high-speed sampling for closed-loop motor current/voltage sensing. |
| DAC | 2-channel 10-bit R-2R - provides analog reference or bias generation for sensor excitation or actuator control signals. |
| Low-Power Modes | Six modes including Deep Standby RTC/Stop with RAM retention - extends battery life in portable industrial monitors and smart sensors. |
| Clock Sources | Five sources: 4–48 MHz main oscillator, 32.768 kHz sub-clock, 4 MHz/100 kHz CR oscillators, Main PLL - enables precise timing across sleep/wake transitions. |
Pinout & Package
Package: 80-pin LQFP (12 mm × 12 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Core and I/O power domains (2.7–5.5 V); separate analog/digital ground pins reduce noise coupling into ADC/DAC. |
| XTAL / EXTAL | Main crystal oscillator input/output | Supports 4–48 MHz external crystal; enables precise timing for communication interfaces and real-time control loops. |
| RTC_XTAL / RTC_EXTAL | Real-time clock crystal input/output | 32.768 kHz crystal connection for autonomous RTC operation during deep standby modes. |
| SWDIO / SWCLK | Serial Wire Debug I/O and clock | Two-pin debug interface replacing JTAG; allows full programming, breakpointing, and memory inspection without pin overhead. |
| P00–P77 | General-purpose I/O with port relocate | Up to 65 pins configurable as GPIO or peripheral functions; port relocation enables flexible PCB layout without signal routing constraints. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash architecture | Enables background firmware update: one bank executes while the other is erased/written - zero downtime in field-deployed controllers. |
| Hardware CRC accelerator | Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation from CPU - reduces integrity check latency for CAN/LIN message validation and Flash checksum verification. |
| Quadrature Position/Revolution Counter (QPRC) | Two independent 16-bit position + 16-bit revolution counters with configurable A/B/Z input edge detection - eliminates external encoder interface ICs in BLDC/PMSM motor drives. |
| Multi-function serial interface (8 channels) | Each channel independently configurable as UART/CSIO/LIN/I²C with FIFO, baud rate generator, and error detection - consolidates multiple communication protocols on single MCU without external transceivers. |
| Integrated clock supervisor (CSV) + LVD | Detects external clock failure/frequency anomaly and asserts reset or interrupt; LVD1/LVD2 provide interrupt-only and auto-reset voltage monitoring - ensures fail-safe behavior in safety-critical embedded systems. |

FAQ
Does CY9BF122KPMC-GNE2 support in-system programming via SWD?
Yes. The device features a Serial Wire JTAG Debug Port (SWJ-DP) supporting full in-system programming, real-time debugging, and memory inspection using standard Arm-compliant tools like Keil MDK or SEGGER J-Link. SWDIO and SWCLK pins operate at core voltage and require no external level-shifting circuitry.
What is the maximum operating temperature range for CY9BF122KPMC-GNE2?
The CY9BF122KPMC-GNE2 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed in Section 12.2 "Recommended Operating Conditions" of the official datasheet (Document Number 002-05655 Rev. *K), with validated performance across the full range for Flash, SRAM, ADC, and peripheral timing.
Can the dual-bank Flash be used for EEPROM emulation?
Yes. The dual-bank architecture enables reliable EEPROM emulation by dedicating one bank for active code and the other for data storage with wear-leveling algorithms. Cypress/Infineon provides application notes (e.g., AN91182) detailing sector management, erase/write sequencing, and error correction techniques optimized for this device's Flash endurance and timing.
Is the LIN interface compliant with ISO 17987-4 (LIN 2.2a)?
No. The CY9BF122KPMC-GNE2 implements LIN protocol Revision 2.1 only, as explicitly stated in the datasheet (Page 2). It supports mandatory features including break field generation (13–16 bit), sync field, PID, data fields, and checksum - but lacks optional 2.2a enhancements such as enhanced checksum mode or conditional frame support.
