LC72P321

The LC72P321 is designed as one kind of single-chip microcontroller +PLL with on-chip one-time PROM. This device features the same functions, pin assignment and package as the mask ROM and provides an 8K-byte PROM on chip. This device is optimal for the first phases of end product production when production is ramping up and for reducing the switchover time when specifications change.

Features of the LC72P321 are:(1)PROM data option switching: this device optional functions can be specified with PROM data. This allows trial evaluations with the printed circuit board used in the mass-produced end product;(2)8K-byte on-chip PROM: this is a one time programmable 8K-byte PROM;(3)pin assignment and package identical to those in the mask ROM version (pin compatibility).

The absolute maximum ratings of the LC72P321 can be summarized as:(1)maximum supply voltage: -0.3 to +6.5 V;(2)input voltage: -0.3 to VDD+0.3 V;(3)output voltage: -0.3 to VDD+0.3 V;(4)allowable power dissipation: 400 mW;(5)operating temperature: -30 to +70 ;(6)storage temperature: -45 to +125 .
