Product details
Overview
CY9AF155NAPMC-G-JNE2 from Cypress Semiconductor (acquired Spansion) is a 32-bit ARM Cortex-M3 microcontroller with 496 KB upper-bank + 16 KB lower-bank dual-operation Flash, 64 KB on-chip SRAM (32 KB SRAM0 + 32 KB SRAM1), and operates up to 40 MHz. It integrates UART/CSIO/I²C serial interfaces, 24-channel 12-bit ADC (2.0 µs conversion), and supports motor control via PWM, dead-time insertion, and QPRC for position sensing in industrial motion systems.
For engineers reviewing the CY9AF155NAPMC-G-JNE2 datasheet, CY9AF155NAPMC-G-JNE2 pinout, CY9AF155NAPMC-G-JNE2 application, or CY9AF155NAPMC-G-JNE2 equivalent, key selection criteria include dual-bank Flash execution capability, 103 GPIOs in 120-pin LQFP package, RTC with leap-year support, hardware watchdog clocked by 100 kHz CR oscillator, and SWJ-DP debug interface without ETM.
Technical Context
The CY9AF155NAPMC-G-JNE2 implements an ARM Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus a 24-bit SysTick timer. Its memory subsystem features dual-bank Flash enabling concurrent read-while-erase/write operations and two independent SRAM banks (SRAM0 on I/D-code bus, SRAM1 on system bus).
Peripheral integration includes a 8-channel DMA controller with 32-bit addressing, multi-function serial interface configurable per channel as UART/CSIO/I²C, and dedicated motor-control blocks: multi-function timer with DTIF interrupt, PPG timers, and QPRC with AIN/BIN/ZIN edge configuration and dual 16-bit counters.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103VCT6 | ARM Cortex-M3, 72 MHz, 256 KB Flash, 48 KB SRAM, no dual-bank Flash or QPRC | Lacks integrated quadrature counter and dual-bank update capability; requires external encoder IC | Preferred where higher CPU speed is critical and motor position sensing is handled externally |

FAQ
What is the maximum operating frequency and voltage range for CY9AF155NAPMC-G-JNE2?
The CY9AF155NAPMC-G-JNE2 operates at up to 40 MHz across a supply voltage range of 1.65 V to 3.6 V. Its internal PLL accepts 4–48 MHz input from the main oscillator, and the built-in high-speed CR oscillator runs at 4 MHz. The wide VCC range supports direct connection to single-cell Li-ion or 3.3 V regulated rails without level shifting.
Does CY9AF155NAPMC-G-JNE2 support simultaneous Flash read and write operations?
Yes - its dual-operation Flash memory consists of an upper bank (496 KB) and lower bank (16 KB), allowing independent erase, write, and read operations on each bank. This enables background firmware updates and real-time code execution without interruption, a capability confirmed in Section 3.2.1 of MB9AF156RA_DS706-00047.
How many ADC channels does CY9AF155NAPMC-G-JNE2 provide, and what is their conversion speed?
The device integrates two 12-bit successive approximation ADC units supporting up to 24 total input channels. Each conversion completes in 2.0 µs at 2.7–3.6 V supply, with scanning and priority modes supported. FIFO buffers (16-step for scan, 4-step for priority) reduce CPU load during continuous acquisition sequences.
Is CY9AF155NAPMC-G-JNE2 pin-compatible with other members of the MB9A150RA series?
Yes - CY9AF155NAPMC-G-JNE2 shares the same 120-pin LQFP package and pinout with CY9AF154NAPMC-G-JNE2 and CY9AF156NAPMC-G-JNE2. Differences lie in Flash size (496+16 KB vs. 384+16 KB vs. 512+16 KB) and peripheral enablement, allowing hardware reuse across performance tiers within the same PCB design.
