UPD753036A

DATA SHEET µ PD753036, 753036(A) 4-BIT SINGLE-CHIP MICROCONTROLLER MOS INTEGRATED CIRCUIT DESCRIPTION The µPD753036 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. It has an on-chip LCD controller/driver with a larger ROM capacity and extended CPU functions compared with the conventional µPD75336, and can provide high-speed operation at a low supply voltage of 1.8 V. It can be supplied in a small plastic TQFP package (12 × 12 mm) and is suitable for small sets using LCD panels. A stricter quality assurance program applies the µPD753036(A) compared to the µPD753036 (standard model). (In terms of NEC’s quality grading, this is a “special” grade product.) For details of functions refer to the following User’s Manual. µPD753036 User’s Manual: U10201E FEATURES Low voltage operation VDD = 1.8 to 5.5 V Can be driven by two 1.5 V batteries Internal programmable LCD controller/driver Internal A/D converter which can be operated at a low voltage 8-bit resolution × 8 channels (successive approximation type) On-chip memory Program memory (ROM): 16384 × 8 bits Data memory (RAM): 768 × 4 bits Capable of high-speed operation and variable instruction execution time for power saving 0.95, 1.91, 3.81, 15.3 µs (@ 4.19 MHz) 0.67, 1.33, 2.67, 10.7 µs (@ 6.0 MHz) 122 µs (@ 32.768 kHz) Small plastic TQFP (12 × 12 mm) Suitable for small sets such as cameras ...
