Product details
Overview
SAF-XC164D-16F20F BB from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, featuring 128 KB on-chip Flash, 2 KB DPRAM, 4 KB DSRAM, and 2 KB PSRAM. It operates at 20 MHz CPU clock (50 ns instruction cycle), integrates TwinCAN 2.0B (32 message objects), dual ASC/SSC interfaces, CAPCOM1/2/6, GPT12E, RTC, and JTAG-based OCDS debug support. Used in industrial motor control and automotive body electronics requiring deterministic real-time I/O handling.
For engineers reviewing the SAF-XC164D-16F20F BB datasheet, SAF-XC164D-16F20F BB pinout, SAF-XC164D-16F20F BB application, or SAF-XC164D-16F20F BB equivalent, key selection criteria include Flash size vs. execution speed trade-off, CAN node count, peripheral event controller (PEC) channel availability, and RoHS-compliant TQFP-100 package thermal performance under 85 °C ambient.
Technical Context
The SAF-XC164D-16F20F BB implements the C166SV2 16-bit CPU with 5-stage pipeline, enabling single-cycle execution for most instructions and 1-cycle 16×16 multiply. Its memory subsystem includes separate 128 KB Flash program memory and three SRAM blocks (DPRAM, DSRAM, PSRAM) mapped into a unified 16 MB linear address space.
Real-time capability is reinforced by an 8-channel Peripheral Event Controller (PEC), 16-priority interrupt system with 50 ns sample rate, and dedicated hardware modules: TwinCAN with gateway functionality, CAPCOM6 for PWM generation, and GPT12E with five independent timers. Clock generation uses an on-chip PLL configurable for 20 MHz operation from external crystal or oscillator input.
Key Specifications

Pinout & Package
SAF-XC164D-16F20F BB is housed in a 100-pin Green TQFP (Thin Quad Flat Package) with 0.5 mm lead pitch, JEDEC MS-026AC compliant, RoHS certified. Thermal resistance ΘJC = 12.5 K/W and ΘJL = 18.0 K/W per datasheet revision V1.2 (2006).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI / VSS | Digital I/O power supply / ground | Separate 3.3 V domain for port pins; requires local decoupling near XTAL1 and P0–P7 |
| XTAL1 / XTAL2 | Crystal oscillator input / output | XTAL1 belongs to VDDI domain; accepts 1–20 MHz fundamental-mode crystals or external clock source |
| TRST | JTAG test reset | Active-low asynchronous reset for OCDS logic; must be pulled high during normal operation |
| P0.0–P0.15 | Port 0 bidirectional I/O | Configurable as general-purpose I/O or alternate functions (e.g., CAN0_TX/RX, ASC0_TxD/RxD) |
| EA | External address enable | Enables external bus interface; low = external memory access active, high = internal memory only |
Key Features
| Feature | Design Value |
|---|---|
| Peripheral Event Controller (PEC) | 8-channel DMA-like transfer engine with 24-bit addressing - eliminates CPU overhead for ADC-to-memory or CAN-to-SRAM transfers |
| CAPCOM6 Unit | 6-channel capture/compare + 1 dedicated compare channel - generates precise center-aligned PWM for 3-phase motor gate drivers |
| GPT12E Timer Unit | Five independent 16-bit timers with reload, capture, and pulse-width modulation modes - supports encoder position tracking and time-stamped event logging |
| Real-Time Clock (RTC) | Independent 32.768 kHz oscillator input with calendar registers - maintains date/time across sleep modes without external components |
| Power Management Modes | Idle, Sleep, Power Down with selective peripheral wake-up - reduces current to <10 µA in Power Down while retaining RAM content |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit real-time microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XC164CS-16F40F | Higher 40 MHz CPU clock, same 128 KB Flash and peripheral set, but uses C166SV2E core with enhanced MAC unit | Supports faster control loops (e.g., servo positioning) but requires higher power budget and tighter layout for signal integrity | Select when >20 MIPS throughput is required and thermal design accommodates increased ΘJC |
| SAF-XC2267-104F80L | 32-bit TriCore™ core, 80 MHz, 1 MB Flash, integrated Ethernet MAC, no TwinCAN - different architecture and toolchain | Targets next-generation gateways needing TCP/IP stack offload and multi-protocol convergence | Choose only for new designs where software migration to TriCore and extended memory footprint are acceptable |
Compared with SAF-XC164D-16F20F BB, the XC164CS-16F40F delivers double instruction throughput at cost of higher dynamic power, while the XC2267-104F80L shifts to 32-bit architecture with Ethernet but abandons CAN dual-node capability - making SAF-XC164D-16F20F BB optimal for cost-sensitive, CAN-centric industrial control where deterministic 20 MHz timing suffices.

FAQ
What is the maximum operating temperature range for SAF-XC164D-16F20F BB?
The SAF-XC164D-16F20F BB is rated for operation from –40 °C to +85 °C ambient temperature, as confirmed in Table 1 of the V1.2 datasheet. This range applies to both commercial and industrial-grade variants, with thermal derating not required up to the upper limit under specified PCB copper area and airflow conditions.
Does SAF-XC164D-16F20F BB support in-application programming (IAP) of its Flash memory?
Yes - the device supports in-system programming (ISP) and in-application programming (IAP) via its on-chip bootstrap loader and JTAG OCDS interface. Flash sectors can be erased and reprogrammed while the CPU executes from other memory regions, enabling field firmware updates without external programmers.
Is the TwinCAN module in SAF-XC164D-16F20F BB compatible with ISO 11898-1:2015 physical layer requirements?
No - the TwinCAN module implements the CAN protocol per ISO 11898-1:2003 (Rev. 2.0B), supporting standard and extended frames at bit rates up to 1 Mbps. Physical layer compliance depends on external transceiver selection (e.g., Infineon TLE6250); the MCU itself provides only the protocol controller and message RAM.
Can SAF-XC164D-16F20F BB operate without an external crystal?
Yes - it supports external clock input (0–20 MHz) directly on XTAL1, bypassing the internal oscillator circuitry. The device also allows internal RC oscillator startup for initial boot, though this is not recommended for CAN or RTC operation due to ±5% frequency tolerance; crystal or ceramic resonator is required for time-critical peripherals.
