Product details
Overview
CY9AF144NBBGL-GK9E1 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 256 KB dual-bank Flash, 32 KB on-chip SRAM (16 KB SRAM0 + 16 KB SRAM1), and operation up to 40 MHz. It integrates UART/CSIO/I²C interfaces, 24-channel 12-bit ADC (2.0 μs conversion), 8-channel DMA, RTC, HDMI-CEC, and six low-power modes - deployed in industrial motor control and smart sensor nodes requiring deterministic real-time response.
For engineers reviewing the CY9AF144NBBGL-GK9E1 datasheet, CY9AF144NBBGL-GK9E1 pinout, CY9AF144NBBGL-GK9E1 application, or CY9AF144NBBGL-GK9E1 equivalent, key selection criteria include dual-bank Flash for seamless firmware updates, 5 V-tolerant GPIO support, hardware CRC acceleration (CRC16/CRC32), and SWJ-DP debug interface compatibility with standard ARM toolchains.
Technical Context
This MCU implements an 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 without contention.
The peripheral architecture includes eight base timers (configurable as PWM/PPG/reload/PWC), dual watchdogs (hardware clocked by 100 kHz CR oscillator, active in Stop/Deep Standby modes), and a dedicated HDMI-CEC controller with automatic ACK generation and arbitration loss detection - all operating within 1.65–3.6 V supply range and qualified for industrial temperature (-40°C to +85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, 40 MHz max - enables deterministic interrupt latency & RTOS support |

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 CEC support and dual-bank update capability; requires external components for robust remote control functions | Select when higher CPU speed and larger SRAM are prioritized over field-upgradable firmware and integrated CEC |
| RP2040 | Dual-core ARM Cortex-M0+, 2 MB Flash, 264 KB SRAM, no hardware CRC or CEC, USB host/device | No industrial temp grade, no hardware watchdog with CR clock, lacks analog precision (no 12-bit ADC) | Prefer for cost-sensitive consumer IoT where USB connectivity and dual-core flexibility outweigh industrial reliability requirements |
Compared with STM32F103VCT6 and RP2040, CY9AF144NBBGL-GK9E1 uniquely combines dual-bank Flash for safe firmware updates, integrated HDMI-CEC for consumer electronics interoperability, and industrial-grade low-power operation - making it optimal for embedded systems requiring both real-time control and protocol offload.

FAQ
Does CY9AF144NBBGL-GK9E1 support in-system programming via SWJ-DP?
Yes. The device supports full in-system programming and debugging through its Serial Wire JTAG Debug Port (SWJ-DP), compatible with standard ARM CoreSight tools. Flash programming can be performed without removing the chip from the board, and the dual-bank architecture allows one bank to execute code while the other is being reprogrammed - enabling zero-downtime firmware updates in deployed systems.
What is the maximum operating temperature range for this MCU?
CY9AF144NBBGL-GK9E1 is rated for industrial temperature operation from –40°C to +85°C. This rating is validated per JEDEC JESD22-A104 and confirmed in the datasheet's Recommended Operating Conditions section. The package (100-pin LQFP) and internal thermal design ensure reliable operation under continuous load at maximum ambient temperature with standard PCB copper pour.
Can the 12-bit ADC operate simultaneously across all 24 channels?
No. While the device has 24 ADC input channels, the two 12-bit SAR ADC units share resources and cannot sample all channels simultaneously. The ADC supports scanning mode (up to 16-step FIFO) and priority conversion (4-step FIFO), but total conversion throughput is limited by the 2.0 μs per sample rate and shared analog front-end - simultaneous sampling requires external multiplexing or external ADCs.
Is external bus interface available on this part number?
No. CY9AF144NBBGL-GK9E1 does not support the External Bus Interface (EBI). Per the datasheet footnote on page 2, EBI is excluded from CY9AF141LB, CY9AF142LB, and CY9AF144LB variants. This part relies on on-chip Flash/SRAM and serial peripherals (UART/CSIO/I²C) for memory and peripheral expansion - reducing PCB complexity and component count for compact designs.
