Infineon Technologies SAK-XC2287-56F66L34 AC

Overview

SAK-XC2287-56F66L34 AC from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 family, featuring an 80 MHz CPU, 448 KB on-chip Flash, 16 KB PSRAM, and operation across –40 °C to 125 °C. It integrates MultiCAN (5 nodes), six serial interfaces (UART/LIN/SPI/IIC/IIS), dual 10-bit ADCs (24 channels total), and CCU6x PWM units. It targets automotive powertrain and chassis control systems requiring deterministic real-time response and high-temperature reliability.

For engineers reviewing the SAK-XC2287-56F66L34 AC datasheet, SAK-XC2287-56F66L34 AC pinout, SAK-XC2287-56F66L34 AC application, or SAK-XC2287-56F66L34 AC equivalent, key selection criteria include CAN node count, Flash/PSRAM sizing, extended temperature grade, CCU6 module availability, and LQFP-144 package compatibility with automotive PCB layouts.

Technical Context

The XC2287 implements a five-stage pipelined C166-compatible CPU core with 12.5 ns instruction cycle at 80 MHz, supporting single-cycle 32-bit arithmetic and MAC operations. Its memory subsystem includes 448 KB Flash (with ECC), 16 KB PSRAM, 16 KB DSRAM, 2 KB DPRAM, and 1 KB SBRAM - all accessible within a unified 16 MB linear address space.

Peripheral integration centers on deterministic real-time control: two synchronizable 10-bit ADCs (≤1 µs conversion), up to four CCU6 modules for independent PWM generation, a 128-object MultiCAN controller (Rev. 2.0B), and six USIC channels configurable as UART, LIN, SPI, IIC, or IIS - all managed via Peripheral Event Controller (PEC) for zero-CPU-overhead data transfers.

FAQ

Does SAK-XC2287-56F66L34 AC support AEC-Q100 qualification?

Yes, the SAK-XC2287-56F66L34 AC is qualified to AEC-Q100 Grade 1 (–40 °C to +125 °C), with full test reports covering HTOL, TC, UHAST, and ESD per JEDEC standards. This qualification is documented in Infineon's official product change notifications and qualification summaries for the XC2287 derivative series.

What debug interfaces does this MCU support?

The SAK-XC2287-56F66L34 AC supports JTAG-based On-Chip Debug Support (OCDS) compliant with IEEE 1149.1, enabling full real-time debugging, trace, and flash programming. It does not support SWD or cJTAG; JTAG pinout (TCK/TMS/TDI/TDO/TRST) is fixed and non-reconfigurable per datasheet Section 3.5.

Can the internal PLL generate clocks other than 80 MHz?

No - the internal PLL is configured to produce only an 80 MHz system clock from the input crystal or external clock source. The PLL multiplier and divider settings are factory-trimmed and not user-programmable; alternative frequencies require external clock generation or use of prescaler divisions downstream of the PLL output.

Is the 448 KB Flash organized as a single bank or multiple sectors?

The 448 KB Flash is divided into 14 sectors of 32 KB each, supporting independent erase operations. Each sector can be erased individually without affecting others, enabling safe over-the-air (OTA) firmware updates with rollback capability and wear-leveling strategies in bootloader implementations.
