Product details
Overview
SAX-XC878CM-13FFA 5V AC 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 an embedded 2.5 V voltage regulator for core logic, with I/O ports operable at 5 V. It supports CAN 2.0B via MultiCAN, 10-bit 8-channel ADC, and dual UARTs - deployed in automotive body control modules requiring deterministic real-time response.
For engineers reviewing the SAX-XC878CM-13FFA 5V AC datasheet, SAX-XC878CM-13FFA 5V AC pinout, SAX-XC878CM-13FFA 5V AC application, or SAX-XC878CM-13FFA 5V AC equivalent, key selection considerations include its 52 KB protected Flash memory, 5 V-tolerant I/O capability, MultiCAN interface compliance, and integrated CORDIC coprocessor for efficient trigonometric computation in motor control loops.
Technical Context
The XC878CM implements a two-clock-per-machine-cycle 8051-compatible CPU core with dual data pointers and hardware multiplication/division (MDU) plus CORDIC acceleration for real-time angle/sine/cosine calculation. Its memory protection strategy includes flash bank locking and password-protected write access to critical registers.
It features a configurable clock generation unit supporting external crystals (1–20 MHz), internal RC oscillator, and PLL-based frequency multiplication up to 26.67 MHz. The power supply system integrates a 2.5 V LDO for core logic while allowing independent 5 V I/O supply - enabling direct interfacing with legacy 5 V sensors and actuators without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | XC800 (8051-compatible), 2-clock/machine cycle → zero-wait-state execution at max frequency |
| Flash Memory | 52 KB with memory protection and lock bits → secure firmware storage and field update safety |
| RAM / XRAM | 256 B on-chip RAM + 3 KB XRAM → sufficient for real-time task stacks and buffered CAN message handling |
| ADC | 10-bit, 8-channel, programmable sampling rate → precise analog sensing for battery voltage, temperature, and position feedback |
| MultiCAN Interface | Two CAN 2.0B controllers with message objects and FIFO support → concurrent communication on chassis and powertrain networks |
| Operating Voltage | I/O: 4.5–5.5 V; Core: 2.5 V (internally regulated) → robust operation across automotive battery fluctuations |
| Max Clock Frequency | 26.67 MHz (PLL-enabled) → deterministic timing for LIN slave response ≤ 15 ms and PWM generation up to 100 kHz |

| VDDIO / VSSIO | I/O power supply / ground | 5 V supply domain - enables direct connection to 5 V peripherals without level translation |
| VDDCORE / VSS | Core logic supply / common ground | 2.5 V supplied internally by embedded LDO - decouples core noise from I/O switching transients |
Key Features
| Feature | Design Value |
|---|---|
| CORDIC Coprocessor | Hardware-accelerated sine/cosine/arctan computation in ≤ 20 cycles - eliminates software lookup tables and reduces motor FOC loop latency by >60% |
| MultiCAN Module | Dual independent CAN 2.0B controllers with 32 message objects each - supports simultaneous communication on comfort and powertrain networks |
| Memory Protection | Flash lock bits + password register + boot ROM isolation - prevents unauthorized firmware overwrite and ensures bootloader integrity |

FAQ
Does SAX-XC878CM-13FFA 5V AC support CAN FD?
No. This device implements MultiCAN compliant with ISO 11898-1:2003 (Classical CAN 2.0B only), supporting bit rates up to 1 Mbps and 29-bit identifiers. CAN FD frame format, CRC enhancements, and variable data length are not supported - confirmed in Section 3.21 of the V1.5 datasheet.
What is the maximum operating temperature range for this part?
The SAX-XC878CM-13FFA 5V AC is qualified for −40 °C to +125 °C ambient temperature, meeting AEC-Q100 Grade 2 requirements. Thermal derating begins above 105 °C case temperature, and junction temperature must remain below 150 °C under all operating conditions per Section 4.1.3.
Is there a factory-programmed bootloader in the Boot ROM?
Yes. The 8 KB Boot ROM contains a factory-programmed, read-only bootloader supporting UART-based firmware updates via the UCB (User Configuration Block) interface. It validates checksums and enforces flash lock bit status before programming - detailed in Sections 3.2.1 and 3.7.2 of the datasheet.
Can the CORDIC unit operate independently of the CPU core?
Yes. The CORDIC coprocessor executes trigonometric and hyperbolic functions autonomously once configured via dedicated registers (CORDICxCON, CORDICxDAT). It generates interrupts upon completion and supports chained operations without CPU intervention - described in Section 3.12 and Register Map Table 3.2.4.3.
