CY9AF142MBPMC-G-JNE2

Microcontrollers Overview

The CY9AF142MBPMC-G-JNE2 is a 32-bit microcontroller from the Infineon FM3 MB9A140NA series, built on the ARM Cortex-M3 core. It operates at frequencies up to 40 MHz and features 160 KB of Flash memory with dual-bank operation and 16 KB of SRAM. The device includes an External Bus Interface supporting up to 8 chip selects and 256 MB address space. Connectivity options include Multi-function Serial Interfaces (UART, CSIO, I2C), DMA, and multiple timers. It supports a supply voltage range of 1.65 V to 3.6 V and is housed in an 80-LQFP package.

Microcontrollers Feature Summary

• Dual-operation Flash memory allows simultaneous erase, write, and read operations across upper and lower banks.
• Integrated External Bus Interface supports SRAM and NOR Flash devices with up to eight chip selects.
• Multi-function Serial Interfaces provide selectable UART, CSIO, or I2C modes with hardware flow control capabilities.
• Low-power consumption modes include Sleep, Timer, RTC, Stop, and Deep Standby configurations.

Microcontrollers Applications

• Embedded controllers requiring low power consumption
• Industrial applications utilizing external bus interfaces for memory expansion
• Systems requiring HDMI-CEC or remote control receiver functions
• General-purpose embedded processing with high-speed serial communication needs

Microcontrollers Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to ensure correct package type and temperature rating. Confirm that the component matches the MB9A140NA series specifications. Check for moisture sensitivity levels and handling precautions prior to assembly. Ensure compatibility with existing design constraints regarding pinout and peripheral availability.

Microcontrollers Selection Notes

Select this model when dual-bank Flash operations are required for performance optimization. The presence of an External Bus Interface distinguishes it from variants lacking this feature. Consider the 80-pin LQFP package dimensions and pin count relative to system I/O requirements. Verify that the 40 MHz operating frequency meets the application's timing constraints.

Microcontrollers Part Context

This component belongs to the CY9A140NB Series, which integrates ARM Cortex-M3 processors with diverse peripheral sets. The series is designed for cost-effective embedded solutions with competitive power profiles. Variants within the family differ primarily in Flash capacity, pin count, and peripheral inclusion such as the External Bus Interface.

Microcontrollers Replacement Considerations

Substitutes must match the ARM Cortex-M3 architecture and 160 KB Flash capacity. Verify pin compatibility if replacing within the same package family. Ensure the replacement part supports the External Bus Interface if utilized in the original design.
