Overview
DATA SHEET µPD70208H, 70216H V40HLTM, V50HLTM 16/8, 16-BIT MICROPROCESSOR MOS INTEGRATED CIRCUIT DESCRIPTION The µ PD70208H (V40HL) is a high-speed, low-power 16-/8-bit microprocessor based on the µ PD70208 (V40TM) with 16-bit architecture, 8-bit data bus, and general-purpose peripheral functions.
The µ PD70216H (V50HL) is a high-speed, low-power 16-bit microprocessor based on the µ PD70216 (V50TM ) with 16bit architecture, 16-bit data bus, and general-purpose peripheral functions.
The V40HL and V50HL offer 20 MHz operation, and in addition to the conventional standby functions, also allows the clock to be stopped by the use of fully static internal circuitry, thus achieving greatly reduced power consumption.
It is also capable of 3 V operation in addition to the previous 5 V operation, making it ideally suited to battery driven systems.
Details are given in the following manuals.
Be sure to read when carrying out design work.
