Infineon SAB80C515A-N18-T3 8-Bit Microcontroller Datasheet and Technical Specifications

The Infineon SAB80C515A-N18-T3 is a powerful, high-performance member of the 8-bit microcontroller family based on the industry-standard 8051 architecture. This device is engineered to deliver enhanced processing capabilities and a rich set of integrated peripherals, making it a versatile solution for a wide array of demanding embedded control applications in the industrial, automotive, and consumer electronics sectors.

Manufactured using advanced CMOS technology, the microcontroller achieves an excellent balance of high speed and low power consumption. Its core operates at a clock frequency of up to 18 MHz (N18), enabling it to execute instructions significantly faster than the original 8051 core. A key architectural enhancement is the inclusion of a pipelined instruction execution unit, which boosts throughput by concurrently fetching and executing instructions.

Memory configuration is a standout feature of the SAB80C515A. It integrates 16 KB of mask-programmable ROM for non-volatile code storage and 512 bytes of on-chip RAM for data handling. This substantial memory space on the chip reduces the need for external memory components, simplifying board design and lowering overall system cost.

The peripheral set is exceptionally comprehensive. It includes:

Five 8-bit I/O ports, providing ample digital interface lines for connecting to sensors, actuators, and other external devices.

Two standard 16-bit timer/counters, plus an additional 16-bit timer/counter with capture and compare capabilities, which is essential for precise event timing, waveform generation, and motor control.

A 14-source interrupt unit with two priority levels, ensuring responsive handling of both internal and external asynchronous events.

A full-duplex serial communication interface (UART),

An 8-channel, 10-bit Analog-to-Digital Converter (ADC), which is critical for acquiring data from analog sensors and transducers without requiring external conversion chips.

The device is offered in a P-LCC-68 plastic leaded chip carrier package, suitable for robust commercial and industrial environments. Its operating temperature range and robust design make it a reliable choice for automotive and industrial control systems.

ICGOOFind Summary: The Infineon SAB80C515A-N18-T3 is a highly integrated and powerful 8-bit microcontroller that excels in complex embedded applications. Its strengths lie in its high-speed 8051 core, generous on-chip memory, and a rich set of integrated peripherals, including a multi-channel ADC. This combination provides designers with a single-chip solution that maximizes functionality while minimizing external component count and system cost.
