MB87069
MB87069 is Serial Interface Adapter manufactured by Fujitsu Semiconductor Limited.
April 1986 Edition 1.0
DESCRIPTION
The Fujitsu MB87069 is a dedicated Serial Interface Adapter (SIA) that provides cost-effective interface support between the Fujitsu MB8764 Digital Signal Processor (DSP). PCM CODECs. and general purpose microprocessors. Some interface examples are shown later in this document.
Features
- Supports M88764 for interface of PCM CODEC and microprocessor
- Serial 1/0 functions (dual input/output lines)
- Conversion circuits for JJ-law/A-law data to linear data and vice-versa
- Interface cirgf Jit for microprocessor
- Software-controlled operations from M88764 or microprocessor
- Silicon~gate CMOS process
- 64-pin Pin Grid Array (PGA) package
PGA-64C-A02
This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields. However, it is advised that normal precautions be taken to avoid application of any voltage higher than maximum rated voltages 10 this high impedance...
