UPD17705 Overview
Provided with a wealth of hardware, these microcontrollers are available in many variations of ROM and RAM capacities to support various applications. Therefore, a high-performance, multi-function digital tuning system can be configured with only one chip. In addition, a one-time PROM model, µ PD17P709, which can be written only once and therefore is ideal for program evaluation and small-scale production of a µ...
