87C51FA : Three different Single-Chip 8-Bit Microcontroller families are presented in this datasheet: FEATURES • 80C32/8XC52/8XC54/8XC58 • 80C51FA/8XC51FA/8XC51FB/8XC51FC • 80C51RA+/8XC51RA+/8XC51RB+/8XC51RC+/8XC51RD+ For applications requiring 4K ROM/EPROM, see the 8XC51/80C31 8-bit CMOS (low voltage, low power, and high speed) microcontroller families datasheet. All the families are Single-Chip 8-Bit Microcontrollers manufactured in advanced CMOS process and are derivatives of the 80C51 microcontroller family. All the devices have the same instruction set as the 80C51. These devices provide architectural enhancements that make them applicable in a variety of applications for general control system.
87C51FA : VCC Supply voltage VSS Circuit ground VSS1 Secondary ground (in PLCC only) Provided to reduce ground bounce and improve power supply by-passing NOTE This pin is NOT a substitute for VSS pin (pin 22) Port 0 Port 0 is an 8-bit open drain bidirectional I O port As an output port each pin can sink several LS TTL inputs Port 0 pins that have 1’s written to them float and in that state can be used as high-impedance inputs 270961 – 2 Example AN87C51FA FB FC indicates an automotive temperature range version of the 87C51FA FB FC in a PLCC package with 16 Kbyte 32 Kbyte EPROM program memory Figure 2 Package Options Table 1 Temperature Options Temperature Classification Extended Automotive Temperat.
