DESCRIPTION
The µPD70208H (V40HL) is a high-speed, low-power 16-/8-bit microprocessor based on the µPD70208 (V40TM) with 16-bit architecture, 8-bit data bus, and general-purpose peripheral functions.
The µPD70216H (V50HL) is a high-speed, low-power 16-bit microprocessor based on the µPD70216 (V50TM) with 16-bit 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.
