General Description
BU34675 General Description
The BU34675 is a compact 4-bit, single-chip microcontroller that includes all the I / O required for CD system control.
Circuits on the chip include a pulse width measurement counter (PWC), SIO, and an LCD controller / driver for a 28-segment display. The LCD segments can all be switched in software to CMOS output, and the extensive I / O allows many functions with a low pin count.
BU34675 Maximum Ratings
| Parameter | Symbol | Limits | Unit |
| Maximum applied voltage | VDD | 0.3 ~ + 7.0 | V |
| Operating temperature | Topr | 25 ~ +75 | |
| Power dissipation | Pd | 500 | mW |
| Storage temperature | Tstg | 55 ~ + 125 | °C |
* Reduced by 5mW for each increase in Ta of 1 over 25
BU34675 Features
1) Low-voltage, high-speed operation (VDD = 2.3 to 5.5V at 4.4MHz).
2) Pulse width measurement counter on chip (for remote control reception).
3) SIO provided for communication with the DSP.
4) Seven-segment, four-common LCD controller / driver on chip.
5) All segments of the LCD controller / driver output can be switched to CMOS output using software.
