Microchip 8-Bit Flash MCU, DIP8

The Microchip 8-Bit Flash MCU is a fully-static Flash-based CMOS microcontroller that employs a RISC architecture with only 33 single-word and single-cycle instructions. All instructions execute in a single cycle, except for programme branches which require two cycles. The 12-bit wide instructions are highly symmetrical, resulting in a typical 2:1 code compression over other 8-bit microcontrollers in its class, while the easy-to-use instruction set significantly reduces development time.

Equipped with special features designed to reduce system cost and power requirements, this microcontroller includes a Power-on Reset (POR) and Device Reset Timer (DRT) that eliminate the need for external reset circuitry. It also boasts low-power high-speed flash technology and a fully static design, alongside a remarkably low sleep current of just 100nA.

Key Features

• Baseline core with 33 instructions and 2 stack levels
• 8-bit wide data path with 25mA source/sink current I/O
• One 8-bit timer (TMR0) and Watchdog Timer (WDT)
• In-Circuit Serial Programming (ICSP) and In-Circuit Debugging support
• Programmable code protection

Electrical & Mechanical Specifications

The device operates on a supply voltage ranging from 2V to 5.5V, with a maximum operating frequency of 4MHz. It features 768Byte of programme memory and 25Byte of RAM memory, alongside 6 I/O lines. Housed in an 8-pin DIP through-hole package, it is AEC-Q100 qualified, ensuring suitability for demanding environments. The physical dimensions are 43mm in height, 33mm in width, and 15mm in depth, with a lightweight design of just 0.83 grams.

This microcontroller is highly versatile and suitable for a wide range of applications, particularly in security, industrial, and automotive sectors.
