Product details
Overview
CY9AF155NBPMC-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 embedded HMI systems.
For engineers reviewing the CY9AF155NBPMC-G-JNE2 datasheet, CY9AF155NBPMC-G-JNE2 pinout, CY9AF155NBPMC-G-JNE2 application, or CY9AF155NBPMC-G-JNE2 equivalent, key selection criteria include dual-bank Flash execution capability, 5 V-tolerant I/O support on selected pins, hardware CRC acceleration (CRC16/CRC32), SWJ-DP debug interface, and deep-standby RTC mode with RAM retention.
Technical Context
This MCU implements an 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 features independent I-code/D-code buses for SRAM0 and system bus for SRAM1, enabling concurrent instruction fetch and data access.
The peripheral set includes a 8-channel DMA controller with 32-bit addressing, multi-function serial interface configurable per channel as UART/CSIO/I²C (up to 16 channels), and dedicated motor-control blocks: PWM, PPG, dead-time insertion, and A/D activation compare - all synchronized via shared clock domains and trigger routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max operation - enables deterministic real-time task execution with low-latency interrupt response. |
| Flash Memory | 512 KB dual-bank Flash (496 KB upper + 16 KB lower), 0-wait-state read - supports background erase/write while executing from opposite bank. |
| SRAM | 64 KB total (32 KB SRAM0 on I/D bus + 32 KB SRAM1 on system bus) - allows parallel code/data access without bus contention. |
| ADC | 24-channel 12-bit SAR ADC, 2.0 µs conversion time @ 2.7–3.6 V - suitable for fast closed-loop current/voltage sensing in motor drives. |
| Timers | 16-channel base timer (PWM/PPG/reload/PWC), 3×16-bit free-run, 4×input capture, 6×output compare - provides full waveform generation and encoder position capture. |
| Low-Power Modes | Six modes including Deep Standby RTC with optional RAM retention - extends battery life in always-on sensor or remote control applications. |
| Debug Interface | Serial Wire JTAG Debug Port (SWJ-DP) - enables full-cycle debugging, flash programming, and real-time trace without dedicated JTAG pins. |
Pinout & Package
Package: LQM120 (120-pin LQFP, 14 mm × 14 mm, 0.4 mm pitch). Pinout validated per CY9A150RB Series datasheet Rev. *F, pages 9–10 (LQM120 assignment) and "List of Pin Function" section (pages 15–38).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Core I/O supply (1.65–3.6 V); separate analog/digital ground pins reduce noise coupling into ADC and RTC. |
| XTAL / EXTAL | Main crystal oscillator input/output | Supports 4–48 MHz external crystal; enables precise timing for USB, communication, and motor control loops. |
| OSC32K / OSC32KIN | 32.768 kHz sub-clock oscillator | Drives RTC and wake-up timers in Stop/Deep Standby modes; maintains timekeeping during ultra-low-power operation. |
| MD0 | Boot mode select | Determines boot source (Flash or ROM) at reset; must be pulled high or low externally per system configuration. |
| INITX | External reset input | Active-low asynchronous reset pin; used for system-level fault recovery or watchdog-initiated hard reset. |
| P00–P57 | General-purpose I/O with port relocation | Up to 103 GPIOs; port relocate function allows dynamic mapping of UART/I²C/ADC functions to alternate pins for PCB layout flexibility. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash architecture | Enables Over-The-Air (OTA) firmware updates without halting application execution - critical for field-deployed industrial controllers. |
| Hardware CRC accelerator | Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation from CPU - reduces firmware validation latency in communication and storage integrity checks. |
| Quadrature Position/Revolution Counter (QPRC) | 16-bit position + 16-bit revolution counters with configurable A/B/Z input edge detection - directly interfaces with incremental encoders in servo and BLDC motor systems. |
| HDMI-CEC/Remote Control Reception | Integrated CEC transmitter/receiver + 4-byte IR buffer with repeat-code detection - eliminates need for external protocol ICs in smart TV and AV receiver designs. |
| Two independent watchdogs | Hardware watchdog (CR oscillator-clocked) remains active in all low-power modes except Deep Standby RTC/Stop - ensures fail-safe recovery even during extended sleep. |
Applications

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 |
|---|---|---|---|
| STM32F103VCT6 | 72 MHz Cortex-M3, 256 KB Flash, 48 KB SRAM, no dual-bank Flash or QPRC; lacks HDMI-CEC and hardware CRC. | Targeted at cost-sensitive general-purpose control; not suitable for encoder-based motion control or CEC-enabled AV systems. | Select when higher CPU speed is needed but advanced motor/peripheral integration is unnecessary. |
| RA4M1 (R7FA4M1AB3CFM) | 48 MHz Cortex-M4F, 256 KB Flash, 32 KB SRAM, no dual-bank Flash; includes TrustZone but no QPRC or CEC. | Focused on secure IoT edge nodes; lacks native encoder interface and consumer electronics protocol support. | Prefer for security-critical wireless sensor hubs requiring cryptographic acceleration over motor control features. |
Compared with STM32F103VCT6 and RA4M1, CY9AF155NBPMC-G-JNE2 uniquely combines dual-bank Flash for robust OTA, QPRC for direct encoder interfacing, and integrated HDMI-CEC - making it optimal for industrial motion control and smart AV equipment where firmware reliability and protocol integration reduce system complexity.

FAQ
What is the maximum operating frequency and voltage range for CY9AF155NBPMC-G-JNE2?
The CY9AF155NBPMC-G-JNE2 operates at up to 40 MHz across a supply voltage range of 1.65 V to 3.6 V. Its internal PLL supports clock multiplication from 4–48 MHz main clock inputs, and the built-in high-speed CR oscillator delivers 4 MHz for clock fallback. All timing specifications in the datasheet are guaranteed within this voltage and frequency envelope.
Does CY9AF155NBPMC-G-JNE2 support in-system programming and debugging?
Yes - it supports full in-system programming and debugging via the Serial Wire JTAG Debug Port (SWJ-DP), compatible with standard Arm CoreSight tools. No external bootloader is required; flash programming can be performed through SWD using vendor-agnostic debuggers such as Segger J-Link or ST-Link v2 clones with appropriate firmware.
How does the dual-bank Flash architecture enable firmware updates?
Dual-bank Flash allows one bank (e.g., upper 496 KB) to run active firmware while the other (lower 16 KB work area) is erased and reprogrammed. This enables seamless Over-The-Air updates without application interruption or external memory - verified in CY9A150RB Series application notes AN94527 and AN95012.
Which pins are 5 V tolerant and how is that confirmed?
Selected GPIO pins (e.g., P00–P07, P10–P17, P20–P27, P30–P37, P40–P47, P50–P57) are 5 V tolerant when configured as inputs. This is explicitly documented in the "I/O Circuit Type" section (page 65) and "List of Pin Function" table (pages 15–38) of the CY9A150RB Series datasheet Rev. *F, and verified on LQM120 package pinouts.
