1 / 56 page  4-BIT SINGLE-CHIP MICROCONTROLLER MOS INTEGRATED CIRCUIT µPD753304 The information in this document is subject to change without notice. Document No. U11874EJ1V0DS00 (1st edition) Date Published October 1997 N Printed in Japan DESCRIPTION The µPD753304 is one of the 75XL series 4-bit single-chip microcontroller chips and has a data processing capability comparable to that of an 8-bit microcontroller. Since it inherits the 75X series CPU, it has upward compatibility. While the conventional 75X series products with an on-chip LCD controller/driver use an 80-pin package, the µPD753304 is sold as a pellet/wafer to make it possible to be built into portable devices with an LCD display function, etc. For detailed function descriptions, refer to the following user’s manual. µPD753304 User’s Manual: U12020E FEATURES • RC oscillation circuit on chip · Main system clock: fCC = 3.6 MHz (typical value with 6.8-k Ω external resistor connected. An internal 10-pF (typ.) capacitor is provided.) · Subsystem clock : fCT = 47 kHz (typ.) (Both a resistor and a capacitor are provided internally.) • Processing can be started immediately after standby mode is released. • Oscillation of the subsystem clock can be stopped in STOP mode. • Supply voltage: VDD = 2.5 to 5.5 V • On-chip memory · Program memory (ROM) : 4096 × 8 bits · Data memory (RAM) : 256 × 4 bits • Variable instruction execution time function useful for power saving · 1.1, 2.2, 4.4, 17.8 µs (in fCC = 3.6 MHz operation) · 85.1 µs (in fCT = 47 kHz operation) • Programmable LCD controller/driver on chip • Sold as a pellet/wafer to make it possible to be built into portable devices with an LCD display function APPLICATION Small LCD display device, etc. ORDERING INFORMATION Part Number Package µPD753304P-XXX Pellet µPD753304W-XXX Wafer Caution The µPD753304 is sold as a pellet/wafer. However, an ES product in 42-pin ceramic shrink DIP is also available. Remark XXX is a ROM code suffix. For the pellet/wafer, consult NEC because an agreement concerning quality must be made. The mark shows major revised points. © 1997 DATA SHEET |
