4-BIT SINGLE-CHIP MICROCOMPUTER

DATA SHEET MOS INTEGRATED CIRCUIT µPD75336 4-BIT SINGLE-CHIP MICROCOMPUTER DESCRIPTION The µPD75336 is one of the “75X-series” 4-bit single-chip microcomputers enabled to process data with performance equivalent to that of 8-bit microcomputers. The µPD75336 is a microcomputer with an expanded capacity of the ROM and RAM of conventional µPD75328 and an improved 8-bit data processing capacity. It can carry out A/D converter low-voltage operations. For evaluation purposes for system development or small-quantity production, the µPD75P336 is available which is a product with the on-chip mask ROM of µPD75336 replaced with a one-time PROM. Functions are described in detail in the following User’s Manual, which should be read when carrying out design work. µPD75336 User’s Manual: IEU-725 FEATURES • µPD75328 upward compatible • Instruction execution time variable function useful for high-speed operations and power saving • 0.95, 1.91, 3.81, 15.3 µs (Main system clock: When operated at 4.19 MHz) • 122 µs (Subsystem clock: When operated at 32.768 kHz) • Memory capacity: µPD75336 ROM: 16256 × 8 bits RAM: 768 × 4 bits • On-chip 8-bit resolution A/D converter (successive approximation type): 8 channels • Low-voltage operation possible: VDD = 2.7 to 6.0 V • On-chip LCD controller/driver • Maximum of 20 × 4 segments drive possible • Improved timer functions: 4 channels • Improved 8-bit data processing capability • Transfer, add/subtract, increase/decrease and compare possible • Ultra-compact package in use (80-pin plastic TQFP (fine pitch)( 12 mm)) • On-chip PROM (µPD75P336) operative at low voltages available • VDD = 2.7 to 6.0 V APPLICATIONS Cameras, VCR integrated cameras, air conditioners, sphygmomanometers, etc. The information in this document is subject to change without notice.
