Product details
Overview
CY9AF155MBGL-GK9E1 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 CY9AF155MBGL-GK9E1 datasheet, CY9AF155MBGL-GK9E1 pinout, CY9AF155MBGL-GK9E1 application, or CY9AF155MBGL-GK9E1 equivalent, key selection criteria include dual-bank Flash execution-in-place capability, 5 V-tolerant GPIO count (up to 103 pins in 120-pin LQM package), hardware CRC accelerator (CRC16/CRC32), SWJ-DP debug interface, and deep-standby RTC mode with RAM retention.
Technical Context
This MCU implements a tightly coupled 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 an 8-channel DMA controller with 32-bit addressing, multi-function serial interface configurable per channel as UART/CSIO/I²C (with hardware flow control on UART ch.4), and dedicated motor-control blocks: PWM/PPG timers, dead-time insertion, A/D activation compare, and QPRC for encoder position tracking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max - enables deterministic real-time task execution with NVIC interrupt latency under 12 cycles |
| Flash Memory | 512 KB dual-bank (496 KB upper + 16 KB lower), 0-wait-state read - supports simultaneous firmware update and execution |
| SRAM | 64 KB total (32 KB SRAM0 on I/D bus + 32 KB SRAM1 on system bus) - decouples core instruction/data traffic from peripheral DMA transfers |
| 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 full-featured motor control waveform generation and position feedback |
| Low-Power Modes | Six modes including Deep Standby RTC with RAM retention - extends battery life in always-on sensor nodes and remote controllers |

| OSC32K / OSC32KIN | Sub-clock crystal terminals | 32.768 kHz crystal connection for RTC and low-power wake-up - operates independently during Stop/Deep Standby modes |
| MD0 | Boot mode select | Configures boot source (Flash vs. ROM) at power-on reset - critical for secure firmware initialization sequence |
| INITX | External reset input | Active-low asynchronous reset pin - enables system-level fault recovery independent of internal watchdog states |
| PA0–PA15, PB0–PB15, etc. | Multi-function GPIO | Up to 103 pins support port relocation and 5 V tolerance - simplifies interface to legacy 5 V peripherals without level shifters |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash memory | Enables seamless firmware updates: erase/write one bank while executing from the other - eliminates system downtime during field upgrades |
| Hardware CRC accelerator | Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation - reduces CPU load by >90% for communication frame integrity checks |
| Quadrature Position Counter (QPRC) | 16-bit position + 16-bit revolution counters with configurable A/B/Z input edges - directly interfaces to incremental encoders in BLDC/PMSM drives |
| HDMI-CEC controller | Integrated header/block transmission, automatic ACK reply, and arbitration loss detection - enables single-chip remote control for consumer AV equipment |
| Two watchdog timers | Independent hardware (CR oscillator-clocked) and software watchdogs - ensures fail-safe recovery even during deep sleep or clock failure |

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, no dual-bank architecture, no QPRC, no HDMI-CEC | Lacks encoder interface and CEC protocol engine - requires external components for motor position sensing and AV control | Choose when higher CPU speed is prioritized over integrated motor/AV peripherals and field-upgrade safety |
| RA4M1 (R7FA4M1AB3CFM) | 48 MHz Cortex-M4F, 256 KB Flash, 32 KB SRAM, no dual-bank Flash, no CEC, includes TrustZone | Offers floating-point unit and security extensions but omits QPRC and HDMI-CEC - targets secure IoT edge nodes, not AV/motor control | Prefer for secure firmware updates and AI inference tasks where cryptographic acceleration outweighs encoder/CEC integration |
Compared with STM32F103VCT6 and RA4M1, CY9AF155MBGL-GK9E1 uniquely combines dual-bank Flash for safe firmware updates, QPRC for direct encoder interfacing, and HDMI-CEC for consumer electronics control - making it optimal for cost-sensitive, function-integrated embedded controllers in motor and AV domains.

FAQ
What is the maximum operating frequency and supported voltage range?
The CY9AF155MBGL-GK9E1 operates at up to 40 MHz with a supply voltage range of 1.65 V to 3.6 V. Its main clock supports 4–48 MHz external crystals, and the built-in PLL enables precise frequency synthesis. The wide voltage range accommodates both battery-powered and regulated industrial power supplies without external level-shifting circuitry.
Does this MCU support in-system programming and field firmware updates?
Yes - its dual-bank Flash architecture (496 KB upper + 16 KB lower) enables true in-system programming: one bank executes active firmware while the other is erased and reprogrammed. This allows zero-downtime field updates and robust recovery from corrupted firmware images without requiring external programming hardware.
How many I/O pins are 5 V tolerant, and what is their functional scope?
Up to 103 GPIO pins in the 120-pin LQM package are 5 V tolerant, as confirmed in the "I/O Circuit Type" section (page 65) and pin function list. These pins support all peripheral functions - including UART, CSIO, I²C, timers, and ADC inputs - eliminating external level translators when interfacing with legacy 5 V logic or sensors.
Is hardware debug support available, and which interface is implemented?
The device implements Serial Wire JTAG Debug Port (SWJ-DP), compliant with ARM CoreSight standards. It supports full breakpoint, watchpoint, and real-time memory inspection without halting peripheral operation. Unlike earlier FM3 variants, CY9AF155MBGL-GK9E1 does not include Embedded Trace Macrocell (ETM), so instruction trace is unavailable.
