Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-XC164CS-16F20F | Same C166SV2 core, 128 KB Flash, but rated for 20 MHz max CPU clock (50 ns cycle); identical pinout and peripheral set. | Targeted at cost-sensitive, lower-performance applications where 40 MHz timing margin is unnecessary (e.g., body electronics vs. powertrain). | Select when thermal/power budget constraints preclude 40 MHz operation or when legacy software is validated only at 20 MHz. |
| SAF-XC164CS-16F40F | Identical electrical specs and peripherals, but qualified for -40 °C to +85 °C ambient - lacks extended 125 °C qualification and associated screening. | Suitable for cabin-mounted modules (infotainment, telematics), not under-hood powertrain or battery management units. | Choose for non-engine-bay applications where extended temperature grade adds unnecessary cost and qualification overhead. |
Compared with SAK-XC164CS-16F20F and SAF-XC164CS-16F40F, the XC164CS16F40FBBKXUMA1 uniquely combines 40 MHz real-time performance, -40 °C to +125 °C operation, and full TwinCAN gateway capability - making it the only variant qualified for high-dynamics, thermally demanding engine control tasks.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for XC164CS16F40FBBKXUMA1?
The device operates at a maximum CPU clock frequency of 40 MHz, delivering a 25 ns instruction cycle time for single-cycle execution of most instructions. This timing is achieved using the on-chip PLL with external crystal input (e.g., 10 MHz crystal ×4 multiplier). The 5-stage pipeline ensures consistent throughput even with branch-intensive code.
Does XC164CS16F40FBBKXUMA1 support in-system programming (ISP) of its Flash memory?
Yes, it supports ISP via the on-chip bootstrap loader accessible through ASC0 or ASC1 serial interfaces. Flash programming requires standard UART-level signals and specific command sequences defined in the user manual; no external programmer is needed once boot code is resident. Erase/write cycles are rated for ≥10,000 operations.
How many CAN nodes does the TwinCAN module support, and what protocol versions are implemented?
The TwinCAN module implements two fully independent CAN controllers (CAN0 and CAN1), each compliant with ISO 11898-1:2003 (CAN 2.0B Active), supporting both Standard (11-bit) and Extended (29-bit) identifiers. It provides 32 message objects total, configurable per node, and includes hardware gateway functionality for message forwarding between CAN buses.
Is the XC164CS16F40FBBKXUMA1 pin-compatible with other XC164CS derivatives?
Yes, all XC164CS derivatives in the 100-pin TQFP package - including SAK-XC164CS-16F20F, SAF-XC164CS-16F40F, and ROM variants - share identical pinouts and mechanical footprint. Functional differences (e.g., Flash size, temperature grade, clock speed) do not affect PCB layout, enabling hardware reuse across product tiers.
