MB89821PFM-G-123-BND-R

The MB89821PFM-G-123-BND-R is one member of the MB89821 family which is a line of single-chip microcontroller. This device contains a variety of peripheral functions such as timers, a UART, a serial interface, and an external interrupt. The microcontrollers of the MB89821PFM-G-123-BND-R offer a memory space of 64 Kbytes for storing all of I/O, data, and program areas. The I/O area is located at the lowest address. The data area is provided immediately above the I/O area. The data area can be divided into register, stack, and direct areas according to the application.

Features of the MB89821PFM-G-123-BND-R are:(1)minimum execution time:0.8 s/5 MHz (Vcc=+5.0 V);(2)low-power consumption modes;(3)external interrupt: 2 channels;(4)capable of wake-up from low-power consumption modes (with an edge detection function);(5)two serial interfaces 8-bit synchronous serial interface (Switchable transfer direction allows communication with various equipment.) UART (5-, 7-, 8-bit transfer capable);(6)three types of timers;(7)8-bit PWM timer (also usable as a reload timer);(8)8-bit pulse width count timer (also usable as a reload timer);(9)20-bit time-base timer.

The absolute maximum ratings of the MB89821PFM-G-123-BND-R can be summarized as:(1)power supply voltage:Vss-0.3 to Vss+7.0 V;(2)LCD power supply voltage:Vss-0.3 to Vss+7.0 V;(3)"L" level output current:10 mA;(4)storage temperature:-55 to +150 °C;(5)operating temperature:-40 to +85 °C;(6)power consumption:300 mW;(7)total "H" level output current:10 mA.
