Product details
Overview
KX228796F66L82ACXT from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 family, featuring an 80 MHz CPU clock, 768 KB on-chip Flash, 64 KB PSRAM, dual A/D converters (24 total channels, 10-bit, <1 µs conversion), and MultiCAN Rev. 2.0B with up to 5 CAN nodes - deployed in automotive powertrain control units requiring deterministic real-time response.
For engineers reviewing the KX228796F66L82ACXT datasheet, KX228796F66L82ACXT pinout, KX228796F66L82ACXT application, or KX228796F66L82ACXT equivalent, key selection criteria include CAN node count (5), CCU6 module availability (0–3 instances), temperature grade (−40 °C to 125 °C), Flash endurance (100 k erase/write cycles), and JTAG-based OCDS debug support.
Technical Context
The KX228796F66L82ACXT implements a five-stage pipelined C166-compatible CPU core delivering single-cycle 32-bit arithmetic and MAC operations, with 16 Mbyte linear address space and fast context switching via dual local register banks. It integrates two synchronizable 10-bit ADCs with hardware preprocessing and 24-channel input routing.
Its peripheral set includes six serial interface channels (UART/LIN/SPI/IIC/IIS), a 16-channel CAPCOM2 unit, up to four CCU6 modules for PWM generation, GPT12E timers, RTC, and a MultiCAN module supporting 128 message objects across five independent CAN nodes - all operating from a single 3.0–5.5 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

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/ADC specs; differs only in ordering suffix (no functional impact). | No difference - same automotive qualification, pinout, and firmware compatibility. | Select when standard Infineon part numbering is required for BOM alignment. |
| SPC560P50L5 | Power Architecture e200z0 core, 64 MHz, 512 KB Flash, 3 CAN, no CCU6 - lacks multi-phase PWM hardware acceleration. | Suitable for mid-tier powertrain but not for EPS or high-channel-count ADC applications. | Choose only if legacy SPC5 toolchain integration outweighs loss of CCU6 and reduced CAN node count. |
Compared with SAK-XC2287-96F66L, KX228796F66L82ACXT offers identical functionality and qualification; versus SPC560P50L5, it delivers higher CAN node density, integrated CCU6 PWM, and faster ADC - critical for safety-critical motor control and multi-bus gateway designs.

FAQ
What is the maximum operating frequency of the KX228796F66L82ACXT CPU?
The CPU operates at a maximum frequency of 80 MHz, achieving a 12.5 ns instruction cycle time. This is enabled by an on-chip PLL that multiplies an external crystal input (1–20 MHz) with ±0.5% accuracy over the full −40 °C to +125 °C range. The five-stage pipeline supports single-cycle 32-bit arithmetic and MAC instructions essential for engine control loops.
Does KX228796F66L82ACXT support CAN FD?
No - KX228796F66L82ACXT implements CAN 2.0B (Rev. 2.0B active) only, with bit rates up to 1 Mbps. It does not support CAN FD's flexible data-rate or extended payload features. For CAN FD applications, Infineon's later AURIX™ TC2xx or TC3xx families are required.
How many A/D converter channels does this device provide?
KX228796F66L82ACXT provides up to 24 total A/D converter channels: 16 dedicated to one ADC and 8 to the second, both 10-bit with conversion times below 1 µs. Channel routing is configurable via on-chip multiplexers, and both ADCs support hardware-triggered synchronous sampling for correlated measurements.
Is JTAG debug supported, and what capabilities does it offer?
Yes - JTAG supports On-Chip Debug Support (OCDS) with real-time trace, non-intrusive breakpoints, memory inspection, and flash programming. It enables full visibility into CPU registers, peripheral states, and SRAM contents without halting execution - critical for validating timing-critical automotive software during HIL testing.
