Product details
Overview
XC228796F66LACKXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 family, featuring an 80 MHz CPU with five-stage pipeline, 768 KB on-chip Flash, 64 KB PSRAM, and dual A/D converters (24 channels total, 10-bit resolution, <1 µs conversion time). It integrates MultiCAN (Rev. 2.0B, up to 5 nodes, 128 message objects), six serial interface channels (UART/LIN/SPI/IIC/IIS), and CCU6x PWM units. Used in automotive powertrain control and industrial motor drives requiring deterministic real-time response.
For engineers reviewing the XC228796F66LACKXUMA1 datasheet, XC228796F66LACKXUMA1 pinout, XC228796F66LACKXUMA1 application, or XC228796F66LACKXUMA1 equivalent, key selection criteria include CAN node count (5), Flash size (768 KB), operating temperature range (–40 °C to 125 °C), supply voltage (3.0–5.5 V), and JTAG-based on-chip debug support (OCDS).
Technical Context
The XC228796F66LACKXUMA1 implements a C166-family-compatible register-based CPU with two local register banks for fast context switching and zero-cycle jump execution. Its interrupt system supports 16 priority levels across 87 sources, with sample rate down to 12.5 ns and Peripheral Event Controller (PEC) enabling single-cycle data transfers.
Memory architecture includes 1 KB SBRAM, 2 KB DPRAM, 16 KB DSRAM, 64 KB PSRAM, and 768 KB Flash - all mapped into a unified 16 MB linear address space. Clock generation uses internal PLL with external crystal (XTAL1/XTAL2) or oscillator input, supporting multiple low-power modes via programmable power management.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-XC2287-96F66L | Same die, identical Flash/PSRAM/CAN/peripheral set; differs only in marking and tape-and-reel packaging format. | No functional difference; used interchangeably in production where reel packaging is required. | Select when automated SMT placement mandates standard JEDEC-compliant tape configuration. |
| SAK-XC2286-96F66L | Reduces CAN nodes from 5 to 3 and removes CCU6x unit 2/3; retains same CPU, Flash, PSRAM, and ADC specs. | Suitable for cost-sensitive chassis modules (e.g., ABS, airbag) where fewer CAN domains and no advanced PWM are needed. | Choose for non-powertrain applications requiring full 768 KB Flash but lower peripheral integration and BOM cost. |
Compared with SAK-XC2287-96F66L, XC228796F66LACKXUMA1 offers identical functionality but with Infineon's standard industrial-grade tape-and-reel delivery; versus SAK-XC2286-96F66L, it adds two CAN nodes and two CCU6x units - enabling full vehicle network participation and complex motor control not possible on the derivative.

FAQ
Is XC228796F66LACKXUMA1 pin-compatible with other XC228x derivatives?
Yes - all XC228x devices in the 144-pin LQFP package share identical pinout, including XC2287, XC2286, and XC2285 variants. Signal mapping, power pin locations, and JTAG interface pins are fully consistent across the family, enabling hardware reuse across different performance tiers.
What is the maximum allowed crystal frequency for XTAL1/XTAL2?
The datasheet specifies a 1–20 MHz fundamental-mode quartz crystal for XTAL1/XTAL2. Operation above 20 MHz violates AC timing specifications and may cause PLL lock failure or unstable CPU clock generation; external oscillator input is required for higher-frequency reference sources.
Does XC228796F66LACKXUMA1 support AEC-Q100 qualification?
Yes - the SAK- prefix variant (e.g., SAK-XC2287-96F66L) is explicitly qualified to AEC-Q100 Grade 1 (–40 °C to +125 °C). XC228796F66LACKXUMA1 shares the same die and process; its industrial-grade marking reflects identical reliability testing and failure-rate data per Infineon's qualification reports.
Can the on-chip Flash be programmed in-system via JTAG?
Yes - the OCDS JTAG interface supports full in-system programming (ISP) of Flash memory using Infineon's DAS (Debug Access Server) and MemTool software. No external programmer is required; erase/write operations comply with datasheet timing and voltage requirements for endurance (>10k cycles) and data retention (>20 years).
