Product details
Overview
XC8664FRA5VBEAXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core (8051-compatible), featuring 8 KB Flash, 256 B RAM, 10-bit 8-channel ADC, three 16-bit timers, UART, SSC, and CCU6 PWM unit. It operates with 3.3 V I/O supply and 2.5 V core voltage generated by an embedded regulator, targeting automotive body electronics and industrial control applications.
For engineers reviewing the XC8664FRA5VBEAXUMA1 datasheet, XC8664FRA5VBEAXUMA1 pinout, XC8664FRA5VBEAXUMA1 application, or XC8664FRA5VBEAXUMA1 equivalent, key selection considerations include its PG-TSSOP-38 package, LIN-capable UART, brownout reset, power-down wake-up via RXD/EXINT0, and -40 °C to +140 °C extended temperature grade.
Technical Context
The XC8664FRA5VBEAXUMA1 implements a two-clock-per-machine-cycle 8051-compatible core with dual data pointers and integrated memory protection. Its clock system combines an on-chip oscillator with PLL for stable high-frequency operation and includes loss-of-lock detection.
It integrates peripheral subsystems including a full-duplex UART with LIN header support, synchronous serial channel (SSC), 16-bit capture/compare unit (CCU6) for motor control PWM, and a 10-bit ADC with configurable conversion sequence and sample-and-hold timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | XC800 8-bit CPU (8051-compatible), 2 clocks/machine cycle → zero-wait-state memory access at max frequency |
| Flash Memory | 8 KB Flash with memory protection strategy → secure firmware storage and boot integrity enforcement |
| ADC Resolution | 10-bit SAR ADC, 8 input channels → sufficient dynamic range for sensor signal digitization in automotive sensors |
| Operating Voltage | I/O supply: 3.3 V ±10%; core logic: 2.5 V (internally regulated) → enables mixed-voltage interfacing while minimizing core power |
| Temperature Range | -40 °C to +140 °C (SAA grade) → qualified for under-hood automotive environments and industrial thermal extremes |
| Package | PG-TSSOP-38 (38-pin thin shrink small outline package) → surface-mount compatibility with high pin density and thermal performance |
| Reset Sources | Power-on, hardware, brownout (core supply), watchdog, and power-down wake-up → robust system initialization and fault recovery |
Pinout & Package
XC8664FRA5VBEAXUMA1 is housed in a PG-TSSOP-38 package - a 38-pin, thermally enhanced, lead-free thin shrink small outline package with 0.5 mm pitch and exposed thermal pad for improved heat dissipation in high-reliability applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO | I/O Power Supply | 3.3 V supply for all digital I/O ports; decoupling required for noise immunity |
| VDDCORE | Core Logic Supply | 2.5 V internal regulator output; not externally connected - derived from VDDIO |
| P0.0–P0.7 | Port 0 Bidirectional I/O | 8-bit quasi-bidirectional port; also serves as address/data bus during external memory access |
| P1.0–P1.4 | Port 1 Digital I/O | 5-bit general-purpose I/O; P1.0–P1.2 support analog input for ADC |
| P2.0–P2.7 | Port 2 Digital I/O | 8-bit general-purpose I/O; supports EXINT0 interrupt trigger on P2.0 |
| RXD/TXD | UART Serial Interface | Full-duplex asynchronous communication; RXD supports wake-up from power-down mode |
| OSCIN/OSCOUT | Crystal Oscillator Input/Output | Supports external crystal (1–20 MHz) or ceramic resonator; feeds PLL clock generation |
| RESET | Active-Low Reset Input | Asynchronous reset assertion; internal pull-up ensures defined state at power-up |
Key Features
| Feature | Design Value |
|---|---|
| Embedded Voltage Regulator | Generates stable 2.5 V core supply from 3.3 V I/O rail → eliminates need for external core LDO and simplifies PCB layout |
| LIN-Capable UART | Hardware support for LIN 2.0 header transmission and synchronization → reduces CPU overhead in automotive body networks |
| CCU6 Capture/Compare Unit | 16-bit timer with dead-time insertion and center-aligned PWM → enables precise motor phase control in BLDC drivers |
| Memory Protection Strategy | Configurable read/write protection for Flash and XRAM → prevents accidental overwrite of critical firmware or calibration data |
| Power-Saving Modes | Slow-down, idle, and power-down modes with wake-up on RXD or EXINT0 → extends battery life in always-on automotive modules |
Applications
| Automotive Door Module | Industrial Motor Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC886LMAA4VBEAXUMA1 | Same XC800 core, but 16 KB Flash, 512 B RAM, and added CAN 2.0B controller; PG-LQFP-48 package | Requires CAN bus integration (e.g., body control modules with gateway functions); larger footprint and higher pin count | Select when CAN communication and >8 KB code space are mandatory; not drop-in due to package and peripheral differences |
| SAK-TC1766-128F133HR BA | TriCore™ 32-bit MCU with 128 KB Flash, 16 KB RAM, and integrated ADC, CAN, and Ethernet; LQFP-144 | Targets complex real-time control (e.g., engine management); significantly higher performance and integration level | Choose for next-generation designs requiring ASIL-B compliance, multi-core safety features, or advanced diagnostics - not a functional substitute |
Compared with XC8664FRA5VBEAXUMA1, XC886LMAA4VBEAXUMA1 adds CAN and memory but requires board redesign, while SAK-TC1766 represents a platform-level upgrade with no pin or software compatibility - both serve distinct architectural tiers rather than direct replacement roles.

FAQ
Does XC8664FRA5VBEAXUMA1 support in-circuit debugging?
Yes, it includes on-chip debug support via JTAG interface and 1 KB monitor ROM (within the 8 KB Boot ROM). The monitor ROM provides runtime firmware patching and breakpoint handling, while JTAG ID register (address 0xE8) enables identification and boundary-scan testing during development and production test.
What is the maximum ADC sampling rate for XC8664FRA5VBEAXUMA1?
The ADC achieves up to 100 kSPS maximum conversion rate, constrained by the ADC clock (derived from system clock divided by programmable prescaler) and minimum acquisition time. At 16 MHz system clock and optimal configuration, full 10-bit conversions complete in ≤10 μs, enabling real-time sensor monitoring in closed-loop control loops.
Can the embedded voltage regulator be bypassed or disabled?
No - the 2.5 V core regulator is fixed and non-bypassable. VDDCORE is an internal node supplied solely from VDDIO through the integrated regulator; external connection to VDDCORE is prohibited per datasheet Absolute Maximum Ratings. This ensures consistent core voltage under varying I/O load conditions.
Is XC8664FRA5VBEAXUMA1 qualified for automotive safety standards?
It is AEC-Q100 Grade 0 qualified (-40 °C to +140 °C) and designed for automotive applications, but lacks built-in ISO 26262 ASIL certification. Safety-critical functions must be implemented via external monitoring or software-based diagnostic routines - the device supports brownout detection, WDT, and memory protection as foundational safety enablers.
