Product details
Overview
XC87816FFA5VACKXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core, compatible with the standard 8051 instruction set and executing instructions at two clocks per machine cycle. It integrates 52 KB Flash, 3 KB XRAM, 256 B RAM, and 8 KB Boot ROM, with dual-voltage operation (5 V I/O, 2.5 V core via embedded regulator). It targets automotive body electronics and industrial control where LIN, CAN, and analog sensing coexist.
For engineers reviewing the XC87816FFA5VACKXUMA1 datasheet, XC87816FFA5VACKXUMA1 pinout, XC87816FFA5VACKXUMA1 application, or XC87816FFA5VACKXUMA1 equivalent, key selection criteria include its integrated MultiCAN v2.0 controller, 10-bit 8-channel ADC with configurable conversion sequence, CCU6 for motor control PWM generation, and on-chip debug support via JTAG/OCDS.
Technical Context
The XC87816FFA5VACKXUMA1 implements a two-clock-per-machine-cycle 8051-compatible CPU core with dual data pointers and hardware multiplication/division (MDU) plus CORDIC coprocessor for trigonometric computation. Its memory architecture separates 52 KB Flash (with bank pagination and write protection), 3 KB XRAM, and 256 B internal RAM, all accessible without wait states under 26 MHz operation.
Peripherals include a MultiCAN module supporting up to 16 message objects and CAN FD-ready timing, a 10-bit ADC with programmable sampling time and auto-triggering from timers or CCU6, and a CCU6 unit with three independent 16-bit capture/compare channels optimized for 3-phase motor control and center-aligned PWM generation.
Key Specifications

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 |
|---|---|---|---|
| SAK-TC1766-128F133HR BA | 32-bit TriCore CPU, 133 MHz, 1 MB Flash - higher performance but larger footprint and higher power. | Targets complex powertrain or ADAS domains requiring floating-point math and RTOS support. | Select when >100 DMIPS required and cost sensitivity is secondary to functional safety certification (ISO 26262 ASIL-D). |
| XC886CM-8FRAA | Same XC800 core, 32 KB Flash, no MultiCAN - smaller memory and reduced CAN capability. | Suitable for simpler LIN-only nodes like seat position sensors or HVAC actuators. | Select for cost-constrained LIN gateway or sensor nodes where CAN is unnecessary and Flash <40 KB suffices. |
Compared with SAK-TC1766, XC87816FFA5VACKXUMA1 offers lower system cost and power for mid-tier body electronics, while XC886CM provides a pin-compatible migration path for designs scaling down from full CAN+LIN functionality.

FAQ
What is the maximum operating frequency and corresponding supply requirements?
The XC87816FFA5VACKXUMA1 operates up to 26 MHz using an internal PLL locked to an external 1–20 MHz crystal or ceramic resonator. It requires a 5 V ±5% supply on VDDIO and draws core power from its internal 2.5 V regulator - no external core voltage source is needed. The device meets AEC-Q100 Grade 2 specifications across −40 °C to +105 °C ambient.
Does this MCU support CAN FD or only classical CAN?
The XC87816FFA5VACKXUMA1 implements MultiCAN v2.0 compliant with ISO 11898-1:2003, supporting classical CAN (up to 1 Mbps) but not CAN FD frame format or bit-rate switching. Its CAN controller includes 16 message objects, dedicated TX/RX buffers, and hardware acceptance filtering - sufficient for most body domain networks where FD bandwidth is unnecessary.
How is Flash memory protected against accidental overwrite or malicious reprogramming?
Flash protection uses a two-tier scheme: sector-level write/erase lock bits controlled via Flash registers, and a password-protected "flash lock" mechanism requiring a 32-bit key written to the Password Register before any Flash operation. Once locked, reprogramming requires full chip erase - preventing partial corruption or unauthorized firmware injection in deployed systems.
Can the integrated LIN transceiver drive standard LIN bus loads without external components?
Yes - pins P1.6 (LIN_TX) and P1.7 (LIN_RX) implement a full LIN 2.1-compliant physical layer with built-in bus driver, slew-rate control, and short-circuit protection. It directly interfaces with standard LIN bus (12 V supply, 1 kΩ pull-up) and supports baud rates from 1.2 to 20 kbps without external transceiver ICs or discrete components.
