PIC1654S-H

The PIC1654S-H is designed as a MOS/LSI device containing RAM, I/O and a central processing unit as wel as customer-defined ROM on a single chip. This combination produces a low cost solution for applications which require sensing individual inputs and controlling individual outputs. Keyboard scanning, display driving, and other system control functions can be done at the same time due to the power of the 8-bit CPU.

PIC1654S-H has twelve features. (1)32 8-bit RAM registers. (2)512x12-bit program ROM. (3)Arithmetic logic unit. (4)Real time clock/counter. (5)Self contained oscillator for crystal or ceramic resonator. (6)Available to RAM registers inherent to instruction. (7)Available in three temperature range 0°C to 70°C, -40°C to 85°C and -40°C to 110°C. (8)Its 18 pin package. (9)2 level stack for subroutine nesting. (10)Open drain option on all I/O lines. (11)12 bi-directional I/O lines. (12)2us instruction execution time. Those are all the main features.

Some absolute maximum ratings of PIC1654S-H have been concluded into several points as follow. (1)Its ambient temperature under bias would be 125°C. (2)Its storage temperature range would be from -55°C to 150°C. (3)Its voltage on any pin with respect to Vss except open drain would be from -0.3V to 9.0V. (4)Its voltage on any pin with respect to Vss open drain would be from -0.3V to 13V. (5)Its power dissipation would be 800mW. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of PIC1654S-H are concluded as follow. (1)Its power supply voltage would be min 4.5V and max 7.0V. (2)Its primary supply current would be typ 30mA and max 50mA. (3)Its input low voltage would be min -0.2V and max 0.8V. (4)Its input high voltage would be min 2.4V and max Vdd. And so on.
