M37549G1 General Description


The M37549G1 is designed as oe member of the 7549 group which is 8-bit microcomputer based on the 740 family core technology. The 7549 group has an 8-bit timer, 16-bit timer, serial interface, AD converter, power-on reset circuit and the low voltage detection circuit. Also the function set ROM is equipped. M37549G1 applications include office automation equipment, factory automation equipment, home electric appliances, consumer electronics, etc.

M37549G1 has many features and some are listed here. (1)Basic machine language instructions 71. (2)The minimum instruction execution time 0.25us. (3)Memory size 2K, 4K, 6K bytes for ROM and 192/256 bytes for RAM. (4)Programmable IO ports is 19 for IO ports and 1 for output port. (5)Key-on wakeup is 8. (6)LED direct drive port is 8. (7)Interrupts is 12 sources, 12 vectors. (8)Timers is 8-bit x 2 and 16-bit x 1. (9)Output compare 3 channels. (10)input capture is 1 channel. (11) Serial interface 8-bit x 1. (12)AD converter is 10-bit resolution x 8-channel. (13)Clock generating circuit is built-in type. (14)High speed on-chip oscillator is typ 4MHz. (15)Low speed on-chip oscillator is typ 250KHz. (16)Watchdog timer is 16-bit x 1. And so on.

Some absolute maximum ratings of M37549G1 have been concluded into several points as follow. (1)Its power supply voltage would be from -0.3V to 6.5V. (2)Its input voltage would be from -0.3V to Vcc+0.3V. (3)Its output voltage would be from -0.3V to Vcc+0.3V. (4)Its power dissipation would be 300mW. (5)Its operating temperature range would be from -20°C to 85°C. (6)Its storage temperature range would be from -40°C to 125°C.It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

And some electrical characteristics of M37549G1 are concluded as follow. (1)Its high output voltage would be min Vcc-1.5V. (2)Its low output voltage would be max 1.5V. (3)Its hysteresis would be typ 0.5V. (4)Its high input current would be max 5.0uA. (5)Its high input currnt Xin would be typ 4.0uA. (6)Its low input current would be max -5uA. (7)Its low input current RESET would be max -0.7mA. And so on. If you have any question or suggestion or want to know more information about M37549G1 please contact us for details. Thank you!
