P87C552SBAA

The P87C552SBAA is a kind of single-chip 8-Bit microcontroller which is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family.

Features of the P87C552SBAA are:(1)80C51 central processing unit; (2)8k 8 EPROM expandable externally to 64k bytes; (3)an additional 16-bit timer/counter coupled to four capture registers and three compare registers; (4)two standard 16-bit timer/counters; (5)256 8 RAM, expandable externally to 64k bytes; (6)capable of producing eight synchronized, timed outputs; (7)a 10-bit ADC with eight multiplexed analog inputs; (8)fast 8-bit ADC option; (9)two 8-bit resolution, pulse width modulation outputs; (10)five 8-bit I/O ports plus one 8-bit input port shared with analog inputs; (11)I2C-bus serial I/O port with byte oriented master and slave functions; (12)on-chip watchdog timer; (13)extended temperature ranges; (14)full static operation 0 to 16 MHz; (15)Operating voltage range: 2.7V to 5.5V (0 to 16MHz).

The absolute maximum ratings of the P87C552SBAA can be summarized as:(1): storage temperature range is 65 to +150 °C; (2): voltage on EA/VPP to VSS is 0.5 to +13 V; (3): voltage on any other pin to VSS is 0.5 to +6.5 V; (4): input, output DC current on any single I/O pin is 5.0 mA; (5): power dissipation (based on package heat transfer limitations, not device power consumption) is 1.0 W.
