Product details
Overview
SAK-XC866-4FRI BC from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core (8051-compatible), featuring 12 KB of program Flash, 4 KB of data Flash, 256 bytes of RAM, and operating at 5.0 V supply with industrial temperature range (–40 to +125 °C). It integrates a 10-bit 8-channel ADC, three 16-bit timers, CCU6 capture/compare unit for PWM, UART, SSC, and on-chip debug support - deployed in motor control and industrial sensor interface applications.
For engineers reviewing the SAK-XC866-4FRI BC datasheet, SAK-XC866-4FRI BC pinout, SAK-XC866-4FRI BC application, or SAK-XC866-4FRI BC equivalent, key selection criteria include Flash memory partitioning (P-Flash/D-Flash), I/O voltage tolerance (5 V), watchdog timer programmability, CCU6 PWM resolution, and TSSOP-38 package compatibility with industrial thermal requirements.
Technical Context
The XC866 implements a two-clock-per-machine-cycle 8051-compatible core with dual data pointers and embedded 2.5 V core regulator, enabling zero-wait-state execution from on-chip Flash. Its memory architecture separates 12 KB P-Flash (code) and 4 KB D-Flash (data), both protected by configurable bit-level write protection.
Peripheral integration includes a 16-bit CCU6 unit supporting center-aligned PWM generation with dead-time insertion, a full-duplex UART with automatic baud-rate detection, and an 8-channel 10-bit ADC with configurable sampling timing and result alignment - all clock-gated for power management in idle and power-down modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | XC800 (8051-compatible), 2 clocks/machine cycle, enabling zero-wait-state Flash access |
| Program Memory | 12 KB P-Flash: executable code storage with configurable sector protection |
| Data Memory | 4 KB D-Flash: nonvolatile data logging and parameter storage, independent of P-Flash |
| RAM | 256 bytes internal RAM + 512 bytes XRAM: sufficient for real-time control stack and buffer handling |
| ADC | 10-bit, 8-channel SAR ADC with programmable sampling time and left/right-aligned results |
| Timers | Three 16-bit timers (T0/T1/T2) + CCU6: supports PWM generation, input capture, and event counting |
| Supply Voltage | 5.0 V I/O supply with internal 2.5 V core regulator - eliminates external LDO for logic domain |
| Operating Temp | –40 °C to +125 °C (industrial grade): validated for under-hood and factory-floor environments |
Pinout & Package
SAK-XC866-4FRI BC is housed in a PG-TSSOP-38 (38-pin thin shrink small-outline package) with 0.65 mm pitch, thermally enhanced for industrial convection cooling. Pin functions are defined per Infineon's XC866 datasheet Rev. V1.2 (2007), with dedicated VDDP (I/O supply), VDD (core regulator input), and VSS pins routed for low-noise analog/digital separation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0.0–P0.7 | Port 0 bidirectional I/O | 8-bit digital I/O with internal pull-ups; multiplexed with address/data bus during external memory access |
| P1.0–P1.7 | Port 1 bidirectional I/O | 8-bit digital I/O; P1.6/P1.7 serve as XTAL1/XTAL2 for external crystal oscillator |
| P2.0–P2.2 | Port 2 digital I/O | 3-bit general-purpose I/O; P2.0–P2.1 used for UART TXD/RXD in default mode |
| P3.0–P3.2 | Port 3 digital I/O | 3-bit general-purpose I/O; P3.0 = EXINT0 (external interrupt), P3.1 = RXD, P3.2 = TXD (alternate UART) |
| CC60–CC63 | CCU6 output channels | Four dedicated PWM output pins (CH0–CH3) with complementary pair support and dead-time control |
| AD0–AD7 | ADC input channels | Eight analog inputs mapped to P0.0–P0.7 and P1.0–P1.3; share pins with digital I/O |
| VDDP | I/O power supply | 5.0 V supply for all GPIOs and peripheral I/O circuits - decoupling required per datasheet layout guidelines |
| VDD | Core logic supply input | Input to internal 2.5 V regulator; requires external 5.0 V source and local 100 nF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Memory Protection | Configurable bit-level write protection for P-Flash and D-Flash sectors prevents accidental firmware overwrite |
| CCU6 PWM Engine | 16-bit resolution, center-aligned mode, and hardware dead-time insertion enable precise motor phase control |
| Power Management | Three low-power modes (slow-down, idle, power-down) with wake-up via RXD or EXINT0 reduce system standby current |
| On-Chip Debug | 1 KB monitor ROM + 64 B monitor RAM allow in-circuit debugging without external emulator hardware |
| Reset Sources | Five independent reset triggers (POR, HW, BOR, WDT, Power-Down Wake-up) ensure deterministic recovery from fault conditions |

FAQ
What is the maximum operating frequency of the SAK-XC866-4FRI BC core?
The XC800 core runs at up to 26.67 MHz with an external crystal (XTAL1/XTAL2) and internal PLL, delivering 13.33 MIPS performance. The maximum frequency is limited by the 5.0 V supply and industrial temperature range - no derating required up to +125 °C per datasheet timing specifications.
Does the SAK-XC866-4FRI BC support in-system programming (ISP)?
Yes - the device supports ISP via UART using the on-chip bootloader (LIN BSL not enabled; standard UART BSL active). Firmware updates require no external programmer; only a 3.3 V–5.0 V UART interface and valid checksum-protected hex file are needed.
How is Flash memory partitioned between code and data usage?
P-Flash (12 KB) is allocated for executable code; D-Flash (4 KB) is reserved exclusively for nonvolatile data storage. Both regions support independent erase/write cycles and configurable write protection bits - no runtime remapping or overlay is required.
Can the CCU6 unit generate complementary PWM outputs with programmable dead time?
Yes - CCU6 supports complementary channel pairs (e.g., CH0/CH1) with hardware-inserted dead time adjustable in 12.5 ns steps (at 26.67 MHz system clock), preventing shoot-through in half-bridge drivers without CPU intervention.
