Product details
Overview
CY9AF155NPMC-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 CY9AF155NPMC-G-JNE2 datasheet, CY9AF155NPMC-G-JNE2 pinout, CY9AF155NPMC-G-JNE2 application, or CY9AF155NPMC-G-JNE2 equivalent, key selection criteria include dual-bank Flash for seamless firmware updates, 5 V-tolerant I/O 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 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, 8-channel DMA with 32-bit addressing, and dedicated motor-control blocks: PWM/PPG timers, dead-time insertion, A/D activation compare, and QPRC for encoder position tracking - all synchronized via shared clock domains and trigger 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 and NVIC latency under 12 cycles. |
| Flash Memory | 512 KB dual-bank (496 KB upper + 16 KB lower), 0-wait-state read - supports background firmware update without halting application execution. |
| SRAM | 64 KB total (32 KB SRAM0 + 32 KB SRAM1), independently bus-connected - isolates instruction/data access from system peripherals to prevent bus contention. |
| 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. |
| Timers | 16-channel base timer + 3×16-bit free-run + 6×output compare + QPRC - provides synchronized PWM generation, encoder counting, and time-critical event capture in single chip. |
| Low-Power Modes | Six modes including Deep Standby RTC with RAM retention - extends battery life in always-on sensor nodes while preserving context across wake events. |
| Debug Interface | Serial Wire JTAG Debug Port (SWJ-DP) - enables full-speed debugging, flash programming, and trace without requiring external debug probes beyond standard SWD headers. |

Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash architecture | Enables over-the-air firmware updates with zero downtime: erase/write one bank while executing from the other. |
| Hardware CRC accelerator | Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation - reduces CPU load by >90% for communication frame integrity checks. |
| QPRC with configurable edge detection | Directly interfaces quadrature encoders with AIN/BIN/ZIN inputs - eliminates need for external logic or FPGA glue for position feedback in BLDC/PMSM drives. |
| HDMI-CEC transceiver block | Handles header transmission, arbitration loss detection, and automatic ACK reply - simplifies implementation of consumer electronics remote control interoperability. |
| Two independent watchdogs | Hardware watchdog (CR oscillator) remains active in all low-power modes except Deep Standby Stop - ensures fail-safe recovery even during ultra-low-power operation. |

FAQ
What is the maximum operating frequency and voltage range for CY9AF155NPMC-G-JNE2?
The CY9AF155NPMC-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 main clock frequencies from 4 MHz to 48 MHz, but the maximum guaranteed CPU frequency is 40 MHz per the datasheet's AC characteristics table. The wide voltage range enables direct interfacing with both 1.8 V and 3.3 V logic families without level shifters.
Does this MCU support hardware-based firmware updates without application interruption?
Yes. The dual-bank Flash architecture (496 KB upper bank + 16 KB lower bank) allows simultaneous read from one bank while erasing or programming the other. This enables true background firmware updates - critical for industrial systems requiring zero-downtime field upgrades and secure OTA deployment without halting real-time control tasks.
Which pins are 5 V tolerant, and how is tolerance verified?
Selected GPIO pins - including P00–P07, P10–P17, P20–P27, and P30–P37 - are 5 V tolerant when configured as inputs. Tolerance is confirmed in the "List of Pin Function and I/O Circuit Type" section (page 65) of the official datasheet, specifying absolute maximum ratings of −0.3 V to 5.5 V on those pins, independent of VCC level. External series resistors are not required for 5 V signal interfacing.
Is SWD debugging supported, and what debug features are included?
Yes. The CY9AF155NPMC-G-JNE2 supports Serial Wire Debug (SWD) via its Serial Wire JTAG Debug Port (SWJ-DP). It provides full breakpoint/watchpoint support, memory access during halt, flash programming, and register visibility. Unlike earlier FM3 variants, this part includes SWJ-DP compatibility - eliminating the need for legacy JTAG-only debug adapters and enabling use with standard ARM Cortex debug tools.
