The HMS91C8032 and the HMS97C8032 are a member of the HMS9XC8032 series. This devices are the Digital Tuning System(DTS) with PLL. It has extended Intel 8051 core, 32Kbytes one-time programmable(OTP) ROM. Because this device can be programmed by user, it is suited for applications such as the small-scale production of many different products and rapid development and time-to-market of new products.
