SPCP761A
FULL/LOW SPEED USB MCU with MTP

General Description

SPCP761A, a PC peripheral controller designed to satisfy PC peripheral interface requirements, is a cost effective solution that supports USB or PS/2 Keyboard, RF USB receiver applications. SPCP761A cores with 1T 8051 CPU which is capable of running at up to 12MHz clock rate and has a built-in 96MHz oscillator and PLL to provide the system clock and clock output. Additionally, it features 8K bytes of MTP program memory and 1024 bytes of RAM. The SPCP761A not only fulfills all PC peripheral controller requirements, but also includes the full service and support of SunplusIT.
