Description

The P89C668HBA device contains a non-volatile 64 kbytes Flash program memory that is both parallel programmable and serial In-System Programmable.In-System Programming allows P89C668HBA to alter their own program memory, in the actual end product, under software control.

Features of the P89C668HBA are:(1)8051 central processing unit;(2)on-chip FLASH program memory;(3)boot ROM contains low level Flash programming routines for downloading via the UART;(4)can be programmed by the end-user application (IAP);(5)parallel programmed with 87C51 compatible hardware interface to programmer;(6)speed up to 20 MHz with 6 clock cycles per machine cycle;(7)full static operation;(8)RAM expandable externally to 64 kbytes;(9)4 level priority interrupt;(10)8 interrupt sources;(11)four 8-bit I/O ports;(12)full-duplex enhanced UART;(13)power control modes;(14)programmable clock out;(15)second DPTR register;(16)asynchronous port reset;(17)low EMI (inhibit ALE);(18)I2C serial interface;(19)programmable counter array (PCA).

The electrical characteristics of the P89C668HBA can be summarized as:(1):the parameter is operating temperature under bias,the rating is 0 to +70 or -40 to +85,the unit is ;(2):the parameter is storage temperature range,the rating is -65 to +150,the unit is ;(3):the parameter is voltage on EA/VPP pin to VSS,the rating is 0 to +13.0,the unit is V;(4):the parameter is voltage on any other pin to VSS,the rating is -0.5 to +6.5,the unit is V;(5):the parameter is maximum IOL per I/O pin,the rating is 15,the unit is mA;(6):the parameter is power dissipation (based on package heat transfer limitations,not device power consumption),the rating is 1.5,the unit is W.
