HD4074818 Datasheet | Hitachi Semiconductor

Description The H D4 04 81 8 Seri es of 4-bit single-chip HMCS400 series microputers provide high program productivity. It incorporates a large size memory, LCD controller/driver, voltage parator, and 32-k Hz watch oscillator circuit. The HD404818 Series has both standard voltage versions and low voltage versions available. The standard voltage versions operate at 4.0 V to 6.0 V (mask ROM version) and 4.0 V to 5.5 V (PROM version), while the low voltage versions operate at 2.7 V to 6.0 V (mask ROM) and 3.0 V to 5.5 V (PROM). Low voltage versions include an L in their product name. Standard voltage versions: HD404812, HD404814, HD404816, HD404818, HD4074818 Low voltage versions: HD40L4812, HD40L4814, HD40L4816, HD40L4818, HD407L4818 The HD4074818 and HD407L4818, containing PROMs, are ZTAT™ microputers which can dramatically shorten system development time and smoothly proceed from debugging to...
