Description

Electronic Component Model: SAB-C161PI-LM

Product Category: Microcontrollers

The SAB-C161PI-LM is a high-performance 16-bit microcontroller belonging to the C166 family of CMOS microcontrollers. It features a high-performance 16-bit CPU with a 4-stage pipeline, offering an 80 ns instruction cycle time at a 25 MHz CPU clock speed. The microcontroller also provides enhanced boolean bit manipulation facilities and additional instructions to support high-level languages and operating systems. It adopts a register-based design with multiple variable register banks and supports single-cycle context switching. The SAB-C161PI-LM offers a total linear address space of 16 MBytes for code and data, along with an on-chip special function register area of 1024 bytes.

Furthermore, the microcontroller includes a 16-priority-level interrupt system with 27 sources, offering a sample rate down to 40 ns. It also provides 8-channel interrupt-driven single-cycle data transfer facilities via the Peripheral Event Controller (PEC). The clock generation can be achieved via an on-chip Phase-Locked Loop (PLL), prescaler, or direct clock input. The SAB-C161PI-LM is equipped with on-chip memory modules, including 1 KByte of internal RAM (IRAM) and 2 KBytes of extension RAM (XRAM).

For peripheral modules, the microcontroller features a 4-channel 10-bit A/D converter with programmable conversion time down to 7.8 µs. It also includes two multi-functional general-purpose timer units with 5 timers, two serial channels supporting synchronous/asynchronous and high-speed-synchronous communication, and an I2C bus interface with 10-bit addressing and a speed of 400 KHz.

The SAB-C161PI-LM supports up to 8 MBytes of external address space for code and data, offering programmable external bus characteristics for different address ranges. The external address/data buses can be multiplexed or demultiplexed with an 8-bit or 16-bit data bus width. Additionally, the microcontroller provides five programmable chip-select signals.

Other features of the SAB-C161PI-LM include idle and power-down modes with flexible power management, a programmable watchdog timer and oscillator watchdog, an on-chip real-time clock, and up to 76 general-purpose I/O lines with selectable input thresholds and hysteresis. The microcontroller is supported by a wide range of development tools, including C-compilers, macro-assembler packages, emulators, evaluation boards, HLL-debuggers, simulators, logic analyzers, disassemblers, and programming boards. It comes in a 100-pin MQFP/TQFP package.
