GENERAL DESCRIPTION
The MSM6051 is a low-power microcontroller manufactured in complementary metal-oxide
semiconductor technology. Integrated into a single chip are ROM, RAM, crystal oscillator,
voltage doubler, timer, melody circuit, LCD driver, input port, and output port.
Using the on-chip ROM for application code reduces power consumption.
The MSM6051 is widely used in electronic products requiring low-power operation, such as
stopwatches with lap time memory, calculator watches, and handy terminals.
FEATURES
• Low power consumption
• Internal ROM
: 2560 ¥ 14 bits
• Internal RAM
: 120 ¥ 4 bits
• Input port
: 2 ports ¥ 4 bits, 1 port ¥ 1 bit
• Output port
: 1 port ¥ 4 bits
•4 ¥ 4 key matrix input is available by using K1 to K4 and M1 to M4
• 66 LCD drivers (including 3 commons) (1/3 duty, 1/3 bias, 189 segments)
• 59 instructions
• Minimum instruction execution time : 91.5 ms (Display instruction cycle : 183 ms)
• 1.5 V operating voltage (Can be changed to the lithium battery version by mask option)
• Melody function
: Up to 512 notes can be played automatically (with an
envelope)
• Lamp drivers
• Crystal oscillator
: 32.768 kHz
• Chip (102 pads)
