87C52T2

The 87C52T2 is designed as CMOS EPROM version of the 80C52T2, respectively. It includes 8K bytes of EPROM. This user-programmable products is software- and pin-compatible with their ROM-based counterparts.

87C52T2 has seven features. (1)Software and pin compatible with 80C51. (2)Beneficial for prototyping and initial production. (3)All 80C51BH and 80C52T2 features retained. (4)Flashrite EPROM programming. (5)Two level program memory lock. (6)32-byte encryption array. (7)In-circuit test mode facilitates testing. Those are all the main features.

Some absolute maximum ratings of 87C52T2 have been concluded into several points as follow. (1)Its storage temperature range would be from -65°C to 150°C. (2)Its voltage on EA/Vpp pin to Vss would be from -0.5V to 13V. (3)Its voltage on Vcc to Vss would be -0.5V to 6.5V. (4)Its voltage on any other pin to Vss would be from -0.5V to 6.5V. (5)Its power dissipation would be 200mW. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of 87C52T2 are concluded as follow. (1)Its input low voltage except EA would be min -0.5V and max 0.2Vcc-0.1V. (2)Its input low voltage EA would be min 0V and max 0.2Vcc-0.3V. (3)Its input high voltage expect XTAL, RST would be min 0.2Vcc+0.9V and max Vcc+0.5V. (4)Its input high voltage to XTAL, RST would be min 0.7Vcc and max Vcc+0.5V. (5)Its output low voltage ports 1,2,3 would be max 0.45V. (6)Its output low voltage port 0,ALE,PSEN would be max 0.45V. (7)Its output high voltage would be min 2.4V. (8)Its logical 0 input current would be max -50uA. (9)Its logical 1 transition current would be max -650uA. (10)Its input leakage current would be max +/-10uA. (11)Its pin capacitance would be max 1-pF. And so on.
