Product details
Overview
CY9AF142NBBGL-GK9E1 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 256 KB dual-bank Flash, 32 KB SRAM (16 KB SRAM0 + 16 KB SRAM1), and integrated peripherals including 24-channel 12-bit ADC (2.0 μs conversion), 8-channel DMA, UART/CSIO/I²C serial interfaces (up to 8 channels), and six low-power modes. It targets embedded motor control and industrial sensor nodes requiring deterministic real-time response and code security.
For engineers reviewing the CY9AF142NBBGL-GK9E1 datasheet, CY9AF142NBBGL-GK9E1 pinout, CY9AF142NBBGL-GK9E1 application, or CY9AF142NBBGL-GK9E1 equivalent, key selection criteria include dual-bank Flash for safe firmware updates, hardware flow control on UART ch.4, HDMI-CEC transceiver support, RTC with leap-year handling, and 1.65–3.6 V supply range with LVD1/LVD2 monitoring.
Technical Context
This MCU implements the ARM Cortex-M3 r2p1 core at up to 40 MHz with NVIC supporting 48 peripheral interrupts and 16 priority levels. Its memory subsystem features dual-operation Flash (240 KB upper + 16 KB lower bank) enabling concurrent read-while-write, plus two independent SRAM banks-SRAM0 on I/D-code buses and SRAM1 on system bus-for deterministic cacheless execution.
The peripheral set includes a 32-/16-bit dual timer, base timers configurable as PWM/PPG/reload/PWC, HDMI-CEC transmitter with automatic ACK/START/EOM generation, and CRC accelerator supporting CCITT CRC16 and IEEE-802.3 CRC32 for data integrity in communication stacks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M3 r2p1, up to 40 MHz - enables deterministic real-time task scheduling with 24-bit SysTick for OS integration |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state - supports live firmware update without halting execution |
| SRAM | 32 KB total (16 KB SRAM0 + 16 KB SRAM1), independent buses - isolates instruction/data access from system bus traffic |
| ADC | 24-channel 12-bit SAR, 2.0 μs conversion @ 2.7–3.6 V - meets sub-μs sampling requirements for motor current sensing |
| Low-Power Modes | Six modes including Deep Standby RTC/Stop with RAM retention options - extends battery life in always-on sensor endpoints |
| Communication | Up to 8 serial channels (UART/CSIO/I²C), hardware flow control on UART ch.4 - enables robust RS-485 gateway operation |
| Clock Sources | 5 sources: 4–48 MHz main oscillator, 32.768 kHz sub-clock, 4 MHz/100 kHz CR oscillators, Main PLL - ensures clock redundancy and fail-safe timing |
Pinout & Package
CY9AF142NBBGL-GK9E1 is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignment follows CY9A140NB Series standard layout per Document 002-05637 Rev. *D, Page 9–15.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual 1.65–3.6 V supply domains with dedicated analog/digital ground pins - reduces noise coupling in mixed-signal operation |
| XTAL / EXTAL | Main clock oscillator input/output | 4–48 MHz crystal interface with internal load capacitors - eliminates external caps for cost-sensitive designs |
| RTC_XTAL / RTC_EXTAL | Real-time clock oscillator input/output | 32.768 kHz crystal connection for autonomous RTC operation during Stop/Deep Standby modes |
| PA0–PA15, PB0–PB15, etc. | Multi-function GPIO | 83 fast I/O ports with port relocate function and per-pin pull-up - enables flexible PCB routing and peripheral remapping without hardware change |
| AD0–AD23 | Analog input channels | 24 dedicated ADC inputs mapped across multiple ports - supports simultaneous sampling of motor phase currents and temperature sensors |
Key Features
| Feature | Design Value |
|---|---|

| HDMI-CEC transceiver | Hardware-accelerated CEC frame transmission/reception with automatic ACK and arbitration loss detection - simplifies smart home remote integration |
| Hardware watchdog + software watchdog | Independent reset paths: HW watchdog runs on 100 kHz CR oscillator during all low-power modes except Deep Standby RTC/Stop - guarantees fail-safe recovery |
| CRC accelerator | Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation from CPU - reduces interrupt latency in protocol stacks (e.g., Modbus RTU) |
| Port relocate function | Runtime reassignment of peripheral functions (UART, I²C, etc.) to alternate GPIO pins - eliminates board spin for layout optimization |

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 HDMI-CEC | Lacks hardware CEC and concurrent Flash update capability; requires external transceiver for smart home use | Choose when higher CPU speed and larger SRAM outweigh need for CEC or safe firmware update |
| RP2040 | Dual-core ARM Cortex-M0+, 2 MB Flash, 264 KB SRAM, no hardware CEC or analog peripherals | No integrated ADC, RTC, or LVD; relies on software-based CEC stack with higher CPU overhead | Prefer for cost-sensitive consumer devices where dual-core simplicity offsets missing industrial features |

FAQ
Does CY9AF142NBBGL-GK9E1 support JTAG debugging?
Yes, it supports Serial Wire JTAG Debug Port (SWJ-DP) compliant with ARM CoreSight standards. The device does not include Embedded Trace Macrocell (ETM); trace functionality is limited to SWD-based debug and profiling. Debug access remains functional across all low-power modes except Deep Standby Stop.
What is the maximum operating frequency of the ARM Cortex-M3 core?
The core operates at up to 40 MHz, derived from the main clock (4–48 MHz) or Main PLL output. This frequency is validated across the full 1.65–3.6 V supply range and –40°C to +85°C ambient temperature per datasheet Section 12.4.4–12.4.5.
Can the 24-channel ADC perform simultaneous sampling?
No - the 12-bit SAR ADC supports scanning and priority conversion modes but lacks true simultaneous sampling across all 24 channels. It achieves 2.0 μs per conversion with built-in FIFO (16-step for scan, 4-step for priority), enabling rapid sequential acquisition suitable for motor control loop timing.
Is hardware flow control available on all UART channels?
No - hardware flow control (CTS/RTS) is supported only on UART channel 4, as explicitly stated in the datasheet. Channels 0–3 and 5–7 operate in standard UART mode without automatic handshaking, requiring software-based flow management in those configurations.
