Product details
Overview
XC8664FRA3VBELXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core, compatible with the standard 8051 architecture and executing instructions in two clock cycles. It integrates 8 KB Flash, 256 bytes RAM, 512 bytes XRAM, 8-channel 10-bit ADC, UART, SSC, CCU6 PWM unit, and operates across –40 °C to +150 °C for automotive engine control applications.
For engineers reviewing the XC8664FRA3VBELXUMA1 datasheet, XC8664FRA3VBELXUMA1 pinout, XC8664FRA3VBELXUMA1 application, or XC8664FRA3VBELXUMA1 equivalent, this page delivers verified electrical specs, package mapping to PG-TSSOP-38, validated LIN-capable peripheral configuration, and real-world use context for high-temp embedded control design.
Technical Context
The XC8664FRA3VBELXUMA1 implements a two-clock-per-machine-cycle XC800 core with dual data pointers and memory protection via boot ROM locking and bit-level flash protection. Its clock system combines an on-chip oscillator with PLL-based frequency multiplication and loss-of-lock detection for robust timing in noisy environments.
Peripheral integration includes a LIN-compliant UART supporting header transmission, a 16-bit capture/compare unit (CCU6) for motor phase control, and three independent 16-bit timers-T0, T1, and T2-with configurable auto-reload and capture modes. The ADC supports 8-channel, 10-bit conversion with programmable sampling timing and dedicated trigger sources.

FAQ
What is the maximum operating frequency of the XC8664FRA3VBELXUMA1?
The XC8664FRA3VBELXUMA1 supports a maximum CPU clock frequency of 26.7 MHz derived from its internal PLL, which multiplies the external crystal oscillator (typically 1–20 MHz). This enables up to 13.35 million instructions per second (MIPS) due to its two-clock-cycle architecture, confirmed in Section 4.3.4 of the datasheet.
Does XC8664FRA3VBELXUMA1 support in-system programming (ISP)?
Yes, XC8664FRA3VBELXUMA1 supports ISP via its on-chip UART using the built-in bootloader in the 8 KB Boot ROM. Programming requires no external high-voltage signal-only standard 3.3 V/5 V I/O levels and a LIN-compliant host interface, as detailed in Section 3.3 and Application Note AP32064.
Is the ADC capable of simultaneous sampling across multiple channels?
No, the 8-channel 10-bit ADC uses a single successive-approximation converter with multiplexed inputs. It supports sequential conversion triggered by software, timer, or external event-but lacks true simultaneous sampling hardware. Conversion time is 13.5 µs per channel at maximum clock rate, per Section 4.2.3.
What debug interfaces are supported, and is JTAG mandatory for development?
The device supports both JTAG and UART-based on-chip debug via the integrated monitor ROM. JTAG is optional: production programming and basic debugging can be performed over UART using Infineon's DAS (Debug Access Service) protocol, eliminating the need for dedicated JTAG hardware in early prototyping stages.
