Product details
Overview
CY9AF155MBPMC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 512 KB dual-bank Flash (496 KB upper + 16 KB lower), 64 KB on-chip SRAM (32 KB SRAM0 + 32 KB SRAM1), and operation up to 40 MHz. It integrates UART/CSIO/I²C serial interfaces, 24-channel 12-bit ADC (2.0 µs conversion), 16-channel base timer, RTC, QPRC, HDMI-CEC, and six low-power modes - deployed in industrial motor control and smart appliance main control units.
For engineers reviewing the CY9AF155MBPMC-G-JNE2 datasheet, CY9AF155MBPMC-G-JNE2 pinout, CY9AF155MBPMC-G-JNE2 application, or CY9AF155MBPMC-G-JNE2 equivalent, key selection criteria include dual-bank Flash for seamless firmware updates, 5 V-tolerant GPIO support (up to 103 pins in LQFP-120), hardware CRC accelerator (CRC16/CRC32), SWJ-DP debug interface, and sub-3.6 V supply range (1.65–3.6 V).
Technical Context
This MCU implements a tightly coupled Arm Cortex-M3 r2p1 core with integrated NVIC (48 peripheral interrupts + 1 NMI, 16 priority levels) and SysTick timer. Its memory subsystem features dual-operation Flash enabling concurrent read-erase-write across banks, plus two independent SRAM blocks (SRAM0 on I/D-code bus, SRAM1 on system bus) for deterministic real-time execution.
The peripheral set includes a 16-channel multi-function serial interface supporting UART/CSIO/I²C per channel, an 8-channel DMA controller with 32-bit addressing, and dedicated motor-control blocks: PWM/PPG timers, dead-time insertion, A/D activation compare, and QPRC with 16-bit position/revolution counters - all synchronized via shared clock domains and interrupt routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, up to 40 MHz - enables deterministic real-time task scheduling with 24-bit SysTick for OS integration. |
| Flash Memory | 512 KB dual-bank (496 KB upper + 16 KB lower), 0-wait-state read - supports background firmware update without halting execution. |
| SRAM | 64 KB total (32 KB SRAM0 + 32 KB SRAM1), independently bus-connected - isolates instruction/data access from system peripherals to reduce bus contention. |
| ADC | 24-channel 12-bit SAR, 2.0 µs conversion @ 2.7–3.6 V - meets fast-sampling requirements for motor current sensing and sensor fusion. |
| Timers | 16-channel base timer (PWM/PPG/reload/PWC), 32-/16-bit dual timer, QPRC - provides full motor commutation control including dead-time, position feedback, and emergency stop (DTIF). |
| Serial Interfaces | 16-channel multi-function serial (UART/CSIO/I²C), 2× HDMI-CEC, 2× I²C (100/400 kbps) - enables concurrent communication with displays, remote controls, and sensors. |
| Power Supply | 1.65–3.6 V VCC, six low-power modes (Sleep to Deep Standby Stop) - sustains battery-backed RTC and retains RAM state selectively during ultra-low-power operation. |
Pinout & Package
Package: LQFP-120 (14 mm × 14 mm, 0.4 mm pitch), RoHS-compliant, moisture sensitivity level 3. Pin count and I/O allocation confirmed per Cypress Infineon Document No. 002-05646 Rev. *F, Section 3.1 (LQM120) and Section 4 (Pin Function List).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Core & I/O power / ground | Dual-supply domain separation ensures noise immunity between analog (ADC, RTC) and digital logic sections. |
| XTAL / EXTAL | Main crystal oscillator input/output | Supports 4–48 MHz external crystal for precise timing; paired with Main PLL for CPU clock generation. |
| OSC32K / OSC32KOUT | Sub-clock crystal input/output | Drives RTC and watchdog in low-power modes using 32.768 kHz crystal; remains active in Stop and Deep Standby RTC. |
| MD0 | Boot mode select | Configures boot source (Flash/SRAM) at reset; tied high/low externally to define startup vector location. |
| INITX | External reset input | Active-low asynchronous reset pin - used for system-level fault recovery or watchdog-triggered hard reset. |
| PA0–PA31, PB0–PB31, etc. | Multi-function GPIO | Up to 103 pins support port relocation; some are 5 V tolerant - simplifies interface to legacy 5 V peripherals without level shifters. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash memory | Enables over-the-air (OTA) 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 - reduces CPU load by >90% for secure firmware validation and communication integrity checks. |
| QPRC with AIN/BIN/ZIN inputs | Direct quadrature encoder interface with configurable edge detection - eliminates external logic for motor position/speed feedback in BLDC/PMSM drives. |
| SWJ-DP debug interface | Single-pin JTAG/SWD compatibility enables in-circuit debugging and flash programming without dedicated JTAG header footprint. |
| Two-stage LVD (LVD1/LVD2) | LVD1 triggers interrupt for graceful shutdown; LVD2 asserts reset below critical voltage - prevents data corruption during brown-out conditions. |

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 |
|---|---|---|---|
| STM32F103VET6 | 72 MHz Cortex-M3, 512 KB Flash, 64 KB SRAM, no dual-bank Flash or QPRC; lacks HDMI-CEC and hardware CRC. | Requires external encoder interface IC and software CRC; suitable for cost-sensitive general-purpose control where OTA update concurrency is not required. | Select when higher CPU speed is prioritized over motor-specific peripherals and secure firmware validation acceleration. |
| RA4M1 (R7FA4M1AB3CFM) | 48 MHz Cortex-M4F, 256 KB Flash, 32 KB SRAM, no dual-bank Flash; includes capacitive touch IP but no QPRC or HDMI-CEC. | Targets HMI-centric designs; lacks native motor position counter and consumer electronics remote protocol support. | Prefer for touch-enabled UI applications with floating-point math needs, not for encoder-based motion control or CEC-enabled appliances. |
Compared with STM32F103VET6 and RA4M1, CY9AF155MBPMC-G-JNE2 uniquely combines dual-bank Flash for robust OTA, QPRC for direct motor feedback, and HDMI-CEC for consumer electronics interoperability - making it optimal for appliance and industrial motion control where firmware resilience and protocol integration are critical.

FAQ
What debug interface does CY9AF155MBPMC-G-JNE2 support?
It supports Serial Wire JTAG Debug Port (SWJ-DP) only - compatible with standard ARM CoreSight tools. Unlike earlier FM3 variants, it does not include Embedded Trace Macrocell (ETM); trace capability is limited to SWO output and breakpoint/watchpoint debugging via SWD.
Does this MCU support true 5 V-tolerant I/O on all pins?
No - only specific pins (e.g., PA0–PA7, PB0–PB7, PC0–PC7 per Pin Function List in Rev. *F datasheet) are rated for 5 V input tolerance. Other GPIOs operate strictly within 1.65–3.6 V and require level-shifting when interfacing with 5 V peripherals.
Can the dual-bank Flash be used for EEPROM emulation?
Yes - the lower bank (16 KB) is designated as work area and supports byte/word erase and write operations while the upper bank executes code. This enables reliable wear-leveling and data logging without external EEPROM, validated in Cypress Application Note AN91441.
Is the RTC battery-backed, and what power modes retain its operation?
The RTC operates from the 32.768 kHz sub-clock and remains functional in RTC, Stop, Deep Standby RTC, and Deep Standby Stop modes. In Deep Standby RTC mode, it continues counting with optional RAM retention; in Deep Standby Stop, only RTC runs while all SRAM is powered down.
