CY9AF144NBBGL-GK9E1

Microcontrollers Overview

The CY9AF144NBBGL-GK9E1 is a 32-bit microcontroller from the Infineon FM3 CY9A140NB series, based on the ARM Cortex-M3 processor. It features up to 256 Kbytes of dual-bank Flash memory and 32 Kbytes of SRAM. The device operates at frequencies up to 40 MHz with a supply voltage range of 1.65 V to 3.6 V. It includes an External Bus Interface supporting up to 8 chip selects and 256 MB address space. Peripherals include up to 24 channels of 12-bit A/D converters, 8 multi-function serial interfaces (UART/CSIO/I2C), 8 DMA channels, and HDMI-CEC/Remote Control receivers.

Microcontrollers Feature Summary

• Dual-operation Flash memory architecture enabling simultaneous erase, write, and read operations across upper and lower banks.
• Integrated External Bus Interface supporting SRAM and NOR Flash devices with up to 8 chip selects and address/data multiplexing.
• Multi-function Serial Interfaces configurable as UART, CSIO, or I2C with hardware flow control and FIFO buffers.
• HDMI-CEC and Remote Control Receiver units with automatic header transmission, arbitration detection, and repeat code recognition.

Microcontrollers Applications

• Embedded controllers requiring low-power consumption modes
• Systems utilizing external memory expansion via EBI
• Applications requiring HDMI-CEC or remote control signal processing

Microcontrollers Procurement Notes

Verify the specific package variant against the datasheet lineup table, as pin counts and interface availability vary by package type. Confirm that the selected package supports the required External Bus Interface and debug functions, as certain packages like LQD064 lack these features. Ensure compatibility with the 1.65 V to 3.6 V supply voltage range for the target application environment.

Microcontrollers Selection Notes

Select this component when dual-bank Flash operation and external memory interfacing are required within the CY9A140NB series. Note that the External Bus Interface and advanced debug features are not available in all package options; verify the specific package suffix against the datasheet's product lineup to ensure functional requirements are met.

Microcontrollers Part Context

This part belongs to the CY9A140NB Series, which is part of the FM3 family of microcontrollers originally developed by Cypress Semiconductor Corporation. Following Infineon Technologies' acquisition of Cypress, these products continue to be offered under the Infineon portfolio with continuity of ordering part numbers and document content.

Microcontrollers Replacement Considerations

Consult the CY9A140NB Series datasheet Product Lineup section for alternative part numbers within the same family. Variants such as CY9AF141LB or CY9AF142MB offer different memory sizes and pin counts but may lack the External Bus Interface found in the NB series.
