CY7C53150-20AXI

Application Specific Microcontrollers Overview

The CY7C53150-20AXI is a Neuron Chip Network Processor manufactured by Infineon Technologies (formerly Cypress Semiconductor). It implements LonWorks distributed intelligent control networks using three 8-bit pipelined processors for concurrent application and network traffic processing. The device features 512 bytes of on-chip Flash memory, 2 KB of SRAM, and an external memory interface addressing up to 64 KB. Operating at a maximum clock frequency of 20 MHz with a 5.0 V supply, it utilizes a 64-pin TQFP package.

Application Specific Microcontrollers Feature Summary

• Three 8-bit pipelined processors enable concurrent execution of application code and network traffic.
• Integrated 5-pin communication port supports twisted-pair, powerline, RF, IR, fiber-optic, and coaxial transceivers.
• Includes 512 bytes of Flash memory and 2 KB of SRAM for data storage and buffering.
• Features a unique 48-bit ID number for network installation and management.

Application Specific Microcontrollers Applications

• LonWorks node implementation in building automation systems.
• Industrial process control and monitoring applications.
• Smart metering and utility infrastructure networks.

Application Specific Microcontrollers Procurement Notes

Verify the ordering suffix 'AXI' corresponds to the 64-pin TQFP package and lead-free composition. Confirm that the required system firmware version 13 or later is available for external memory programming, as this is mandatory for operation at the specified 20 MHz input clock speed.

Application Specific Microcontrollers Selection Notes

Select this component when external memory expansion beyond 512 bytes is required for complex application logic. Ensure the design accommodates the external memory interface timing requirements, specifically the address and data bus loading constraints for 20 MHz operation. Verify compatibility with the target media transceiver type via the configurable communication port.

Application Specific Microcontrollers Part Context

This device serves as a direct replacement for the Motorola MC143150Bx and Toshiba TMPN3150B1 devices. Unlike the CY7C53120 family which contains on-chip ROM firmware, the CY7C53150 requires system firmware to be stored in off-chip nonvolatile memory such as Flash or EEPROM prior to board assembly.

Application Specific Microcontrollers Replacement Considerations

The datasheet explicitly identifies the CY7C53150 as an exact replacement for the Motorola MC143150Bx and Toshiba TMPN3150B1 devices. No other substitute part numbers are documented in the provided source material.

Application Specific Microcontrollers FAQ

What is the minimum firmware version required for 20 MHz operation?

The firmware in the external memory must be version 13 or later to support the maximum 20 MHz input clock operation.

How does the Low Voltage Inhibit circuit function?

The on-chip LVI circuit trips whenever the VDD input drops below 4.1 ± 0.3 V, preventing corruption of nonvolatile memory during voltage drops.

What are the electrical characteristics of the I/O ports?

I/O0–I/O3 provide a 20 mA sink current capacity. I/O4–I/O7 feature programmable pull-ups. Standard outputs include I/O4–I/O10, CP0, CP1, and CP4.
