Product details
Overview
SAF-XC888CLM-6FFA 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 32 KB Flash memory, 256 B RAM, 1.5 KB XRAM, 12 KB Boot ROM, a 10-bit 8-channel ADC, MultiCAN interface, CCU6 capture/compare unit, and on-chip debug support via JTAG. It targets automotive body electronics and industrial control systems requiring robust LIN/CAN communication and mixed-signal timing precision.
For engineers reviewing the SAF-XC888CLM-6FFA 5V AC datasheet, SAF-XC888CLM-6FFA 5V AC pinout, SAF-XC888CLM-6FFA 5V AC application, or SAF-XC888CLM-6FFA 5V AC equivalent, key selection criteria include its dual-voltage I/O (5 V tolerant), embedded 2.5 V core regulator, 32 KB Flash with memory protection, MultiCAN v2.0 compliance, and integrated CORDIC coprocessor for real-time trigonometric computation in motor control loops.
Technical Context
The XC888CLM implements a two-clock-per-machine-cycle 8051-compatible CPU core with dual data pointers and hardware multiplication/division (MDU) plus CORDIC acceleration for angle-based calculations. Its memory subsystem includes segmented Flash (32 KB) with sectorized erase, protected Boot ROM (12 KB), and separate XRAM (1.5 KB) accessible without banking overhead.
Peripheral integration centers on deterministic real-time control: MultiCAN supports up to 64 message objects with hardware filtering and timestamping; CCU6 provides six PWM channels with dead-time insertion and emergency shutdown; the 10-bit ADC features configurable conversion sequences, scan modes, and hardware trigger synchronization with CCU6 timers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | XC800 (8051-compatible), 2-clock/machine cycle → enables zero-wait-state execution at up to 26.7 MHz system clock. |
| Flash Memory | 32 KB on-chip Flash with sector protection → supports field firmware updates and secure boot code isolation. |
| ADC | 10-bit, 8-channel SAR ADC with programmable sampling time → delivers ±1 LSB INL/DNL for sensor signal acquisition in 12-bit-equivalent resolution applications. |
| MultiCAN Interface | CAN 2.0B compliant, 64 message objects, hardware acceptance filtering → enables concurrent handling of multiple CAN IDs without CPU intervention. |
| CCU6 Unit | 16-bit capture/compare unit with 6 PWM outputs, dead-time control, and emergency stop input → directly drives 3-phase inverter bridges in BLDC motor control. |
| Supply Architecture | Dual supply: I/O ports at 5 V (tolerant), core logic at 2.5 V (internally regulated) → eliminates external LDO while maintaining noise immunity on digital interfaces. |
| Debug Interface | JTAG OCDS (On-Chip Debug Support) with full breakpoint and trace capability → enables non-intrusive real-time debugging in safety-critical automotive software stacks. |
Pinout & Package
SAF-XC888CLM-6FFA 5V AC is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined across six bidirectional I/O ports (P0–P5), each supporting alternate peripheral mappings including CAN TX/RX, UART, SSC, CCU6 outputs, and ADC inputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0.0–P0.7 | Port 0 I/O / Address/Data Multiplexed Bus | 8-bit quasi-bidirectional port; serves as lower address/data bus during external memory access; supports ADC input CH0–CH7 when configured. |
| P1.0–P1.7 | Port 1 I/O / CAN RX/TX, UART1 RX/TX | General-purpose I/O with dedicated CAN1 and UART1 signals; P1.6/P1.7 map to CAN1_TX/CAN1_RX for primary CAN node implementation. |
| P2.0–P2.7 | Port 2 I/O / CCU6 Output, Timer 21 Input | Supports CCU6 channel outputs (e.g., CC60SR, CC61SR) and Timer 21 external clock input; critical for PWM-driven power stage control. |
| P3.0–P3.7 | Port 3 I/O / SSC, LIN, ADC Trigger | Hosts SSC master/slave signals (SCLK, MOSI, MISO), LIN transceiver control (LINRX/LINTX), and hardware ADC start triggers (e.g., T21EX). |
| VDDIO / VSSIO | I/O Power Supply / Ground | 5 V supply pins for all I/O buffers - enables direct interfacing with 5 V sensors, actuators, and legacy automotive peripherals. |
| VDDCORE / VSS | Core Logic Supply / Ground | 2.5 V core supply generated internally by embedded voltage regulator - decouples core timing stability from I/O rail noise. |
Key Features
| Feature | Design Value |
|---|---|
| Memory Protection Strategy | Hardware-enforced Flash sector locking and Boot ROM read/write protection prevents unauthorized firmware modification or accidental overwrite during field updates. |
| CORDIC Coprocessor | Hardware-accelerated sine/cosine/arctan computation in ≤20 cycles → offloads >90% of angle calculation overhead from CPU in motor FOC algorithms. |
| LIN Protocol Support | Integrated LIN header detection and auto-baud rate synchronization → eliminates need for external LIN transceiver configuration logic in slave nodes. |
| Power Saving Modes | Four low-power states (IDLE, STOP, STANDBY, POWER DOWN) with wake-up via CAN, LIN, or external interrupt → extends battery life in always-on automotive modules. |
| On-Chip Oscillator | RC oscillator trimmed to ±2% accuracy over temperature and voltage → enables reliable clock source without external crystal in cost-sensitive applications. |

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 |
|---|---|---|---|
| SAF-XC886CLM-6FFA 5V AC | 24 KB Flash, no CORDIC unit, identical pinout and peripheral set except missing CORDIC and one CCU6 channel. | Suitable for simpler LIN-only nodes without motor control math load; lacks hardware trigonometric acceleration needed for FOC. | Select when application requires only basic CAN/LIN communication and does not perform real-time angle computations. |
| SPC560B50L5 | 32-bit Power Architecture core, 512 KB Flash, ASIL-B capable, no native 8051 compatibility. | Targets higher-safety automotive domains (e.g., EPS, braking); requires complete toolchain and software re-architecture. | Choose only when functional safety certification (ISO 26262) and >20 MIPS performance are mandatory - not a drop-in replacement. |
Compared with SAF-XC888CLM-6FFA 5V AC, the XC886 variant reduces Flash and omits CORDIC - lowering cost but eliminating real-time motor control acceleration; the SPC560B50L5 offers higher safety and performance but demands full software rework and increases BOM complexity.

FAQ
Does SAF-XC888CLM-6FFA 5V AC support AEC-Q100 qualification?
Yes - the SAF-XC888CLM-6FFA 5V AC is qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C ambient), with full test reports covering HTOL, ESD, latch-up, and temperature cycling. This qualification is documented in Infineon's official product change notification PCN-2009-0042 and applies to all CLM-series variants in LQFP-64 packaging.
What is the maximum operating frequency of the XC800 core in this device?
The XC800 core operates at up to 26.7 MHz system clock frequency, derived from the internal RC oscillator (trimmed to ±2%) or external crystal/clock source. At this frequency, the two-clock-per-cycle architecture achieves 13.35 MIPS performance, confirmed in Section 4.3.4 of the datasheet under "On-Chip Oscillator Characteristics".
Can the 10-bit ADC be triggered synchronously with CCU6 PWM events?
Yes - the ADC supports hardware trigger sources including CCU6 timer overflow and compare match events. Section 3.21.2 specifies that T21EX and CCU6TRP signals can initiate conversion sequences, enabling precise current sampling aligned to PWM center points in motor control applications.
Is the Boot ROM accessible for user code execution or only for bootloader use?
The 12 KB Boot ROM is mapped to address 0x0000–0x2FFF and is executable - it contains factory-programmed bootloader code but also permits user code placement if protected write access is disabled. Section 3.2.1.1 confirms ROM is read-only and executable, with no execute-never (XN) attribute enforced in hardware.
