DATA SHEET MOS INTEGRATED CIRCUIT µPD784054(A) 16-BIT SINGLE-CHIP MICROCONTROLLER DESCRIPTION The µPD784054(A) is a product of the 78K/IV series, and based on the µPD784044(A) with the real-time output function and two units of timers/counters deleted and a standby function invalid mode provided. A stricter quality assurance program applies to the µPD784054(A) pared to the µPD784054 (standard model). The µPD784054(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. 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. µPD784054 User’s Manual - Hardware : U11719E 78K/IV Series User’s Manual - Instruction : U10905E Features - Higher reliability pared to the µPD784054 - Minimum instruction execution time - I/O port - Timer - A/D converter - Watchdog timer - Supply voltage : 160 ns (with 12.5-MHz internal clock) - - - µPD784054(A) 200 ns (with 10-MHz internal clock) - - - µPD784054(A1), (A2) : 64 lines : 16-bit timer × 3 units : 10-bit resolution × 16 channels : 1 channel : VDD = 4.5 to 5.5 V - Serial interface UART/IOE (3-wire serial I/O) : 2 channels - Standby function HALT/STOP/IDLE/standby function invalid mode APPLICATION FIELDS Automotive appliances, etc. In this document, in addition to the µPD784054(A), the µPD784054(A1) and 784054(A2) are also explained. However, unless otherwise specified, the µPD784054(A) is treated as the representative model throughout this document. The information in this document is subject to change without notice.
