UPD784044A

DATA SHEET µPD784044(A), 784046(A) 16-BIT SINGLE-CHIP MICROCONTROLLER MOS INTEGRATED CIRCUIT DESCRIPTION The µPD784046(A) is a model in the µPD784046 subseries within the 78K/IV series. A stricter quality assurance program applies µPD784046(A) compared to the µPD784046 (standard model). (In terms of NEC’s quality grading, this is a ”special” grade product.) The µPD784046(A) is provided with many peripheral hardware functions such as ROM, RAM, I/O port, 10-bit resolution A/D converter, timer, serial interface, and interrupt functions, in addition to a high-speed, high-performance CPU. The µPD784046(A) is under development. Moreover, a flash memory model, µPD78F4046Note, that can operate on the same supply voltage as the mask ROM model, and many development tools are under development. Note Use for functional evaluation only. The functions are described in detail in the following User’s Manuals. Be sure to read these manuals when designing your system. µPD784046 Subseries User’s Manual - Hardware : U11515E 78K/IV Series User’s Manual - Instruction : U10905E FEATURES Higher reliability compared to the µPD784044 and 784046 Minimum instruction execution time : 160 ns (with 12.5-MHz internal clock) ··· µPD784044(A), 784046(A) 200 ns (with 10-MHz internal clock) ··· µPD784044(A1), (A2), 784046(A1), (A2) I/O port : 65 lines Timer : 16-bit timer/counter × 2 units 16-bit timer × 3 units A/D converter : 10-bit resolution × 16 channels Serial interface UART/IOE (3-wire se...
