HD404818 Series 4-Bit Single-Chip Microcomputer Preliminary Rev. 2.0 Sept. 1998 Description The H D4 04 81 8 Seri es of 4-bit single-chip HMCS400 series microcomputers provide high program productivity. It incorporates a large size memory, LCD controller/driver, voltage comparator, and 32-kHz 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.
