Product details
Overview
CY9AF142LBQN-G-AVE2 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 - targeting cost-sensitive embedded control in industrial HMI and appliance motor management.
For engineers reviewing the CY9AF142LBQN-G-AVE2 datasheet, CY9AF142LBQN-G-AVE2 pinout, CY9AF142LBQN-G-AVE2 application, or CY9AF142LBQN-G-AVE2 equivalent, key selection criteria include dual-bank Flash for seamless firmware updates, 5 V-tolerant I/O on selected pins, hardware flow control support on UART ch.4, and sub-3.6 V operation with LVD1/LVD2 voltage monitoring.
Technical Context
This MCU implements the 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 CPU and DMA access without contention.
The peripheral set includes eight base timers (configurable as PWM/PPG/reload/PWC), two watchdogs (hardware clocked by 100 kHz CR oscillator, active in Sleep/Timer/RTC modes), and CRC accelerator supporting CCITT CRC16 and IEEE-802.3 CRC32 for data integrity verification in communication and storage paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, up to 40 MHz - enables deterministic real-time control with Thumb-2 instruction set and low-latency interrupt handling. |
| Flash Memory | 256 KB dual-bank (240 KB upper + 16 KB lower), 0-wait-state read - supports background erase/write during code execution for robust OTA updates. |
| SRAM | 32 KB total: 16 KB SRAM0 (I/D bus), 16 KB SRAM1 (system bus) - isolates instruction/data traffic from DMA transfers to prevent bus arbitration stalls. |
| ADC | 24-channel 12-bit SAR, 2.0 µs conversion @ 2.7–3.6 V - delivers high-resolution analog sensing for motor current/voltage feedback in closed-loop control. |
| Low-Power Modes | Six modes including Deep Standby RTC/Stop with RAM retention options - extends battery life in always-on remote control receivers and sensor nodes. |
| Communication | Up to 8 serial channels (UART/CSIO/I²C), hardware flow control on UART ch.4 - ensures reliable host-to-peripheral data transfer in noisy industrial environments. |
| Supply Voltage | 1.65 V to 3.6 V - compatible with single-cell Li-ion, 3.3 V logic rails, and wide-input DC-DC converters in portable and mains-powered systems. |
Pinout & Package
Package: 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dedicated pairs per quadrant minimize IR drop and noise coupling across core, analog, and I/O domains. |
| XTAL / EXTAL | Main clock oscillator input/output | Supports 4–48 MHz crystal or external clock source; enables precise timing for UART baud generation and real-time control loops. |
| OSC32K / OSC32KOUT | 32.768 kHz sub-clock input/output | Drives RTC and Watch Counter independently of main clock - maintains timekeeping during deep sleep with <1 µA current draw. |
| P00–P07, P10–P17, etc. | General-purpose I/O with port relocate | 83 GPIOs total; port relocation allows flexible peripheral mapping (e.g., UART on P30/P31 or P50/P51) without PCB redesign. |
| AD00–AD23 | Analog input channels | 24 dedicated ADC inputs with internal sample-and-hold; some share pins with digital I/O and support 5 V tolerance when configured as inputs. |
| CTS4 / RTS4 | Hardware flow control signals | Only available on UART channel 4 - enables automatic transmission gating in high-throughput serial links without CPU intervention. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash architecture | Enables simultaneous read from one bank while erasing/writing the other - critical for fail-safe firmware updates in field-deployed equipment. |
| Two independent SRAM banks | SRAM0 (I/D bus) and SRAM1 (system bus) eliminate CPU-DMA bus contention - improves deterministic latency in real-time data acquisition. |
| HDMI-CEC transceiver | Integrated header block auto-transmission and ACK reply logic - reduces firmware overhead for consumer electronics remote control interoperability. |
| Hardware watchdog (CR-clocked) | Operates in Sleep/Timer/RTC modes using 100 kHz internal oscillator - ensures system recovery even during low-power states where main clock is stopped. |
| Port relocation capability | Permits runtime assignment of UART, CSIO, or I²C functions to alternate GPIO sets - increases board layout flexibility and simplifies EMI mitigation. |

Use Value: Six low-power modes and 100 kHz CR-clocked watchdog reduce average current to <5 µA; 1.65 V minimum supply extends usable battery range. |
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 integrated CEC and dual-bank update capability; requires external transceiver for HDMI control | Preferred when higher CPU speed and larger SRAM are needed, and CEC is not required |
| RP2040 | Dual-core ARM Cortex-M0+, 2 MB Flash, 264 KB SRAM, no hardware CEC or analog front-end | No built-in ADC, RTC, or CEC; relies on software timing and external peripherals for those functions | Selected for cost-sensitive, high-volume IoT endpoints where USB mass storage boot and PIO flexibility outweigh analog integration |
Compared with STM32F103VCT6 and RP2040, CY9AF142LBQN-G-AVE2 uniquely combines dual-bank Flash for safe firmware updates, hardware-accelerated HDMI-CEC, and 24-channel 12-bit ADC - making it optimal for appliance and industrial HMI designs requiring robust field-upgradability and mixed-signal integration.

FAQ
Does CY9AF142LBQN-G-AVE2 support debug via SWD or JTAG?
Yes, it supports Serial Wire JTAG Debug Port (SWJ-DP) for full debugging and programming. Unlike earlier FM3 variants, this part does not include Embedded Trace Macrocell (ETM); trace functionality is unavailable. Debug access requires standard ARM SWD pins (SWCLK, SWDIO, nRESET, VDD, GND) and is compatible with common tools like Segger J-Link and ST-Link v2 adapters.
What is the maximum operating frequency and associated voltage range?
The CY9AF142LBQN-G-AVE2 operates up to 40 MHz across its full recommended supply range of 1.65 V to 3.6 V. At 40 MHz, the minimum supply voltage is 2.7 V per datasheet Section 12.2. Operation below 2.7 V limits maximum frequency to 20 MHz (1.65–2.7 V range), ensuring stable timing margins and reduced dynamic power consumption in battery-constrained designs.
Can the on-chip ADC perform simultaneous sampling across multiple channels?
No, the 12-bit SAR ADC does not support true simultaneous sampling. It performs sequential conversions with configurable priority and scanning modes. Up to 16-step scanning is supported in SCAN mode with FIFO buffering, and priority conversion allows two groups (high/low) to be interleaved. For synchronized multi-channel capture, external analog front-end circuitry or external ADC with parallel interface is required.
Is external bus interface supported on this variant?
No, CY9AF142LBQN-G-AVE2 explicitly omits External Bus Interface (EBI) support, as confirmed in the datasheet footnote on page 2. This distinguishes it from CY9A140NB series members like CY9AF144LB. Designers requiring external SRAM or NOR flash expansion must use alternative FM3 parts with EBI or implement SPI-based memory extensions using available serial interfaces.
