SAA-XC866L-4FRA 5V BE

Microcontrollers Overview

The SAA-XC866L-4FRA is an 8-bit single-chip microcontroller from the XC800 family, manufactured by Infineon Technologies. It features a high-performance core compatible with the standard 8051 processor, utilizing a two-clock machine cycle architecture for efficient memory access. The device integrates 12 Kbytes of Program Flash and 4 Kbytes of Data Flash within a PG-TSSOP-38 package. It operates with an I/O port supply voltage of 5.0 V and includes an embedded voltage regulator to generate the 2.5 V core logic supply. Key peripherals include an 8-channel 10-bit ADC, three 16-bit timers, a Capture/Compare Unit (CCU6), UART, SSC, and LIN bus support.

• Motor control systems utilizing CCU6 PWM generation

Microcontrollers Procurement Notes

Verify component authenticity through authorized Infineon distributors or direct channels. Confirm the specific ordering suffix matches the required temperature range and package variant. Check current lifecycle status as automotive-grade components may have limited availability or end-of-life notices. Ensure compliance with RoHS directives and moisture sensitivity levels during storage and handling.

Microcontrollers Selection Notes

Select this variant when 12 Kbytes of program memory and 4 Kbytes of data flash are required. The 'L' designation indicates LIN BSL support, essential for local programming without external tools. Choose over non-LIN variants if automotive diagnostic protocols are needed. Ensure the 5V I/O supply aligns with system power rails, noting the internal 2.5V core regulation.

Microcontrollers Part Context

This component belongs to the SAA-XC866 series within the broader XC800 microcontroller family. It shares architectural similarities with other devices in the series but differs in memory configuration and peripheral support. The 'L' suffix specifically denotes support for the LIN Boot Strap Loader, distinguishing it from standard variants like the SAA-XC866-4FRA which lack this feature.

Microcontrollers FAQ

What is the difference between SAA-XC866L-4FRA and SAA-XC866-4FRA?

The primary difference is that the 'L' variant supports the LIN Boot Strap Loader (BSL) for programming, whereas the non-'L' variant does not.

How is the core voltage supplied in this device?

The device uses an embedded voltage regulator to generate the 2.5 V core logic supply from the 5.0 V I/O port supply voltage.
