This datasheet also covers the UPD variant, as both devices belong to the same 4-bit single-chip microcomputer family and are provided as variant models within a single manufacturer datasheet.
General Description
The µPD75308B is a 75X Series 4-bit single-chip microcomputer capable of the same data processing as an 8-bit microcomputer.
It is a low voltage operation version of the µPD75308 with on-chip LCD controller/driver.
Operation at an ultra-low voltage of 2.0 V is possible.
Key Features

N The µPD75308B is a 75X Series 4-bit single-chip microcomputer capable of the same data processing as an 8-bit microcomputer. It is a low voltage operation version of the µPD75308 with on-chip LCD controller/driver. Operation at an ultra-low voltage of 2.0 V is possible. An ultra small-sized plastic QFP (12 × 12 mm) is also provided and it is perfect for small-sized set that uses an LCD panel. Functions, etc., are described in detail in the User's Manual. Please be sure to read this manual when carrying out design work. µPD75308 User's Manual: IEM-5016 FEATURES • Ultra-low-voltage operation possible: VDD = 2.0 to 6.0 V •
