MB89P485L

The MB89P485L is one member of the MB89P480 series that designed as the 8-bit proprietary microcontroller (because of it consists of proprietary 8-bit single-chip microcontrollers). It is designed suitable for LCD remote controller as well as in a wide range of applications for consumer product.

Features of the MB89P485L are:(1)minimum execution time: 0.32 ms at 12.5 MHz;(2)high speed operating capability at low voltage;(3)LQFP package and SH-DIP package;(4)PWC timer (also usable as an interval timer);(5)synchronous/asynchronous data transfer capability;(6)I/O ports: Max 42 channels;(7)edge detection (selectable edge):4 channels;(8)6-bit PPG with program-selectable pulse width and period;(9)low-power consumption mode;(10)watchdog timer reset.

The absolute maximum ratings of the MB89P485L can be summarized as:(1)power supply voltage:Vss-0.3 to Vss+4.0 V;(2)LCD power supply voltage:Vss-0.3 to Vss+6.0 V;(3)input voltage:Vss-0.3 to Vcc+0.3 V;(4)output voltage:Vss-0.3 to Vcc+0.3 V;(5)maximum clamp current:-2.0 to +2.0 mA;(6)total maximum clamp current:20 mA;(7)"L" level maximum output current:15 mA;(8)storage temperature:-55 to +150 °C;(9)operating temperature:-40 to +85 °C;(10)power consumption:300 mW.
