Product details
Overview
CY9AF155MAPMC-G-JNE2 from Cypress Semiconductor (acquired Spansion) is a 32-bit ARM Cortex-M3 microcontroller with dual-bank 512 KB 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/remote control receiver, and six low-power modes - deployed in industrial motor control and embedded HMI systems.
For engineers reviewing the CY9AF155MAPMC-G-JNE2 datasheet, CY9AF155MAPMC-G-JNE2 pinout, CY9AF155MAPMC-G-JNE2 application, or CY9AF155MAPMC-G-JNE2 equivalent, key selection criteria include dual-bank Flash execution capability, 103 GPIOs in 120-pin LQFP package, 5V-tolerant I/O support, hardware CRC accelerator (CCITT CRC16/IEEE-802.3 CRC32), and SWJ-DP debug interface without ETM.
Technical Context
This MCU implements ARMv7-M architecture (Cortex-M3 r2p1 core) with integrated NVIC supporting 1 NMI and 48 peripheral interrupts across 16 priority levels. Its memory subsystem features zero-wait-state Flash access and dual-bus SRAM architecture - SRAM0 connected to I-code/D-code buses for instruction/data caching, SRAM1 on system bus for DMA-accessible buffers.
The peripheral set includes a multi-function serial interface with 16 channels configurable as UART, CSIO, or I²C; a DMA controller with 8 channels supporting byte/half-word/word transfers up to 4 GB address space; and dedicated motor-control blocks including PWM, PPG, dead-time insertion, and A/D activation compare functions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M3 r2p1, 40 MHz max operation - enables deterministic real-time task scheduling in safety-critical firmware. |
| Flash Memory | 512 KB dual-bank (496 KB upper + 16 KB lower), zero-wait-state read - supports background erase/write while executing from opposite bank. |
| SRAM | 64 KB total (32 KB SRAM0 + 32 KB SRAM1), independent bus connections - allows concurrent CPU instruction fetch and DMA data movement. |
| 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. |

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 integrated encoder counter and background Flash update capability - requires external logic for motor position decoding. | Select when higher CPU clock speed is prioritized over motor-control-specific peripherals and field-upgrade resilience. |
| RA4M1 (R7FA4M1AB3CFM) | 48 MHz Cortex-M4F, 256 KB Flash, 32 KB SRAM, no HDMI-CEC or HW WDT with CR clock | Includes FPU and TrustZone but omits CEC/IR receiver and failsafe hardware watchdog - unsuitable for consumer IR ecosystems. | Select when floating-point math or security isolation is required, and CEC/IR functionality is handled externally. |
Compared with STM32F103VCT6 and RA4M1, CY9AF155MAPMC-G-JNE2 uniquely combines dual-bank Flash, QPRC, HDMI-CEC/IR receiver, and CR-clocked hardware watchdog - making it optimal for cost-sensitive, field-upgradable motor and consumer electronics controllers where peripheral integration reduces system-level BOM and validation effort.

FAQ
What is the maximum operating frequency and supported voltage range for CY9AF155MAPMC-G-JNE2?
The CY9AF155MAPMC-G-JNE2 operates at up to 40 MHz with a supply voltage range of 1.65 V to 3.6 V. This wide VCC range enables direct interfacing with both 1.8 V and 3.3 V logic families and supports battery-powered operation down to 1.65 V without brown-out reset.
Does CY9AF155MAPMC-G-JNE2 support in-system programming and debugging?
Yes - it supports Serial Wire JTAG Debug Port (SWJ-DP) with two-pin SWDIO/SWCLK interface. In-system programming is enabled via on-chip bootloader accessible through UART or SWD, allowing firmware updates without external programmers or device removal from the PCB.
How does the dual-bank Flash architecture improve firmware reliability?
Dual-bank Flash allows simultaneous execution from one bank while erasing or programming the other. This enables atomic firmware updates: new code is written to the inactive bank, validated, and then booted from - eliminating risk of bricking during field upgrades and supporting A/B partitioning schemes.
Is the RTC functional in all low-power modes?
The RTC remains operational in SLEEP, TIMER, and STOP modes, and continues counting in Deep standby RTC mode (with optional RAM retention). It is disabled only in Deep standby STOP mode - making it suitable for calendar-based wake-up scheduling across most power-saving states.
