Product details
Overview
SAB-C164CI-LM CA+ from Infineon Technologies is a 16-bit single-chip microcontroller in the C166 family, featuring a 4-stage pipeline CPU, on-chip CAN 2.0B interface with 15 message objects, 2 KB IRAM, 2 KB XRAM, and 8-channel 10-bit ADC with 7.8 µs conversion time. It operates at up to 25 MHz with 5 V supply and targets embedded industrial control systems requiring real-time communication and mixed-signal processing.
For engineers reviewing the SAB-C164CI-LM CA+ datasheet, SAB-C164CI-LM CA+ pinout, SAB-C164CI-LM CA+ application, or SAB-C164CI-LM CA+ equivalent, key selection criteria include CAN 2.0B compliance, 80 ns instruction cycle time, CAPCOM6 PWM capability, PLL-based clock generation (1.5×–5×), and 80-pin MQFP package compatibility with legacy C164 design ecosystems.
Technical Context
The device implements a full-function CAN 2.0B controller with dedicated message object RAM and hardware acceptance filtering, supporting both Basic and Full CAN modes. Its CAPCOM6 unit provides three capture/compare channels and one dedicated compare channel for flexible PWM generation with programmable dead-time insertion.
The peripheral event controller (PEC) enables single-cycle, interrupt-driven data transfers across eight channels, decoupling CPU load from high-speed I/O operations. The on-chip PLL supports multiplication factors of 1.5, 2, 2.5, 3, 4, and 5, allowing precise clock synthesis from external crystal or oscillator inputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit CAN microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAB-C164CI-8R25M | Includes 64 KB on-chip mask ROM; lacks external memory interface flexibility | Fixed firmware deployment only; unsuitable for field-upgradable designs | Select when boot code and application are immutable and external memory cost must be minimized |
| SAK-C164CL-L25M | Reduced-function CAPCOM6 (no CC16–CC19 outputs); same CAN and ADC specs | Limited PWM channel count restricts multi-phase motor control topologies | Select for simpler timing-critical tasks where full CAPCOM6 is unnecessary |
Compared with SAB-C164CI-LM CA+, the SAB-C164CI-8R25M trades external memory expandability for lower BOM cost and boot reliability, while the SAK-C164CL-L25M reduces PWM I/O count to simplify layout and reduce pin count - both retain identical CAN 2.0B and ADC performance but constrain system-level flexibility differently.

FAQ
Does SAB-C164CI-LM CA+ include on-chip program memory?
No. The "LM" suffix denotes a ROM-less derivative. It requires external program memory (e.g., EPROM or Flash) connected via its multiplexed 16-bit address/data bus. Internal memory consists solely of 2 KB IRAM and 2 KB XRAM for runtime data and stack operations.
What is the maximum CAN bit rate supported by this microcontroller?
The on-chip CAN controller supports bit rates up to 1 Mbit/s, compliant with ISO 11898-1:2003. Actual achievable rate depends on bus length, termination, and oscillator accuracy; at 25 MHz CPU clock with PLL ×2, 500 kbit/s is reliably attainable over 100 m.
Can the CAPCOM6 unit generate complementary PWM outputs with dead time?
Yes. CAPCOM6 supports programmable dead-time insertion between complementary PWM outputs (e.g., CC16IO/CC17IO), implemented in hardware without CPU overhead. Dead-time values are set via dedicated CAPCOM6 registers and synchronized to the PWM carrier frequency.
Is the SAB-C164CI-LM CA+ qualified for automotive applications?
It is not AEC-Q100 qualified. While it meets industrial temperature range (–40°C to +85°C) and includes CAN 2.0B, Infineon positioned the C164CI series for industrial and consumer applications; automotive-grade derivatives (e.g., SAF-C164CI variants) require separate qualification and screening.
