SAF-XC164N-32F40F BB

Microcontrollers Overview

The Infineon SAF-XC164N-32F40F BB-A is a 16-bit single-chip microcontroller based on the C166SV2 core. It features 256 Kbytes of on-chip Flash memory and 12 Kbytes of total SRAM (comprising 2 Kbytes DPRAM, 4 Kbytes DSRAM, and 6 Kbytes PSRAM). The device operates at a maximum clock frequency of 40 MHz with a 25 ns instruction cycle time. It includes up to 79 general-purpose I/O lines, two asynchronous/synchronous serial channels, two high-speed synchronous serial channels, and multiple capture/compare units. The component is housed in a 100-pin TQFP package.

Microcontrollers Procurement Notes

Verify the specific ordering suffix and revision level against official Infineon documentation before procurement. Confirm that the intended application environment complies with the specified temperature range and voltage requirements. Check current product lifecycle status as availability may be limited.

Microcontrollers Selection Notes

Select this derivative when 256 Kbytes of Flash memory and 40 MHz processing speed are required. Ensure the system design accommodates the 100-pin TQFP package dimensions. Verify that the available I/O count and peripheral modules meet the specific interface requirements of the target application.

Microcontrollers Part Context

This component belongs to the XC164N family within the broader XC166 microcontroller series. It extends the functionality of previous generations by integrating enhanced peripherals and higher performance capabilities while maintaining compatibility with the C166 instruction set architecture.

Microcontrollers Replacement Considerations

Consult official Infineon cross-reference guides for verified substitutes. Consider derivatives within the same XC164N family or newer generations if pin-to-pin compatibility and feature parity are required.
