Product details
Overview
CY9AF155NABGL-GE1 from Spansion (now Cypress Semiconductor, part of Infineon) is a 32-bit ARM Cortex-M3 microcontroller with dual-bank flash (496 KB + 16 KB), 64 KB on-chip SRAM (32 KB SRAM0 + 32 KB SRAM1), and integrated peripherals including 24-channel 12-bit ADC (2.0 µs conversion), 16-channel base timer, and HDMI-CEC/remote control receiver. It operates at up to 40 MHz and supports six low-power modes including Deep Standby RTC/STOP.
For engineers reviewing the CY9AF155NABGL-GE1 datasheet, CY9AF155NABGL-GE1 pinout, CY9AF155NABGL-GE1 application, or CY9AF155NABGL-GE1 equivalent, key selection criteria include dual-operation flash architecture for seamless firmware updates, 5V-tolerant GPIO (up to 103 pins in 120-pin LQFP), real-time clock with leap-year support, and hardware CRC accelerator for CCITT CRC16 and IEEE-802.3 CRC32.
Technical Context
The CY9AF155NABGL-GE1 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 includes dual-bank Flash enabling concurrent read-erase-write operations and two independent SRAM banks (SRAM0 on I/D-code bus, SRAM1 on system bus).
Peripherals are organized for deterministic real-time control: a 16-channel base timer supports PWM, PPG, reload, and PWC modes; the QPRC block provides 16-bit position/revolution counting with configurable AIN/BIN/ZIN edge detection; and the multi-function serial interface offers 16 channels configurable as UART, CSIO, or I²C with FIFO and hardware flow control on channel 4.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MB9AF156NABGL-GE1 | Same family, 512 KB Flash, identical package and pinout - differs only in Flash bank allocation (496 KB + 16 KB vs. 512 KB uniform). | Requires no PCB change; suitable where full 512 KB contiguous Flash is preferred over dual-bank update capability. | Select when firmware update strategy does not require concurrent bank access and larger contiguous code space is prioritized. |
| STM32F103VCT6 | ARM Cortex-M3, 256 KB Flash, 48 KB SRAM, 100-pin LQFP - lacks QPRC, HDMI-CEC, and dual-bank Flash; adds USB 2.0 FS. | Used in cost-sensitive motor control or sensor nodes where USB host/device is required but CEC/encoder interfaces are absent. | Choose when USB connectivity is mandatory and encoder/CEC functionality is handled externally or omitted. |
Compared with MB9AF156NABGL-GE1, CY9AF155NABGL-GE1 trades uniform Flash layout for guaranteed dual-bank operation essential for safe firmware updates; versus STM32F103VCT6, it delivers specialized peripherals (QPRC, CEC) at the expense of USB, making it superior for embedded AV and precision motion control where those features eliminate secondary ICs.

FAQ
What is the maximum operating frequency and supported voltage range for CY9AF155NABGL-GE1?
The CY9AF155NABGL-GE1 operates at up to 40 MHz across a supply voltage range of 1.65 V to 3.6 V. This wide VCC range supports both battery-powered portable devices and industrial 3.3 V systems without external regulators. The core and peripherals remain fully functional within this window, with timing specifications validated down to 1.65 V at 40 MHz per the MB9AF156RA_DS706-00047 datasheet Rev. 2.0.
Does CY9AF155NABGL-GE1 support hardware debugging, and what interface is used?
Yes, CY9AF155NABGL-GE1 supports Serial Wire JTAG Debug Port (SWJ-DP) for full-cycle development, including breakpoints, register inspection, and flash programming. It does not include Embedded Trace Macrocell (ETM); trace capabilities are limited to SWD packet-level visibility. Debug access remains active in all non-Deep Standby modes, and the SWJ-DP interface uses dedicated TCK/TMS/TDO/TDI/SWCLK/SWDIO pins mapped to physical package pins.
How does the dual-bank Flash architecture enable safe firmware updates?
The dual-bank Flash (496 KB upper + 16 KB lower) allows the application to execute from one bank while erasing, verifying, and writing new firmware to the other. During update, the lower bank serves as work area - enabling background download and validation before atomic bank swap. This eliminates risk of bricking during power loss and satisfies IEC 62443-3-3 requirements for secure firmware deployment in industrial systems.
Which pins are 5V tolerant, and how is this verified?
Specific GPIO pins - including P00–P07, P10–P17, P20–P27, P30–P37, P40–P47, and P50–P57 - are 5V tolerant as confirmed in the "I/O Circuit Type" section of the MB9AF156RA_DS706-00047 datasheet. Tolerance is achieved via internal clamping diodes and reinforced oxide design; absolute maximum rating is 5.5 V on these pins regardless of VCC, enabling direct interface with legacy 5 V logic and sensors without level shifters.
