AN80C51BH

The AN80C51BH is designed as one type of CHMOS microcontroller products which is fabricated on Intel's reliable CHMOS process and is functionally compatible with the standard MCS 51 HMOS microcontroller products.

AN80C51BH has many features. (1)Extended automotive temperature range (-40°C to +125°C ambient). (2)High performance CHMOS process. (3)Power control modes. (3)4Kbyte on-chip ROM/EPROM. (4)128 x 8bit RAM. (5)32 programmable I/O lines. (6)Two 16-bit timer/counters. (7)5 interrupt sources. (8)Quick-pulse EPROM programming. (9)2-level program memory lock EPROM. (10)Boolean processor. (11)Programmable serial port. (12)TTL- and CMOS-compatible logic levels. (13)64K external program memory space. (14)64K external data memory space. (15)IDLE and POWER DOWN modes. (16)ONCE mode facilitates system testing. (17)Available in 12MHz and 16MHz versions. (18)Available in PLCC and DIP packages. Those are all the main features.

Some AN80C51BH absolute maximum ratings have been concluded into several points as follow. (1)Its ambient temperature under bias would be from -40°C to 125°C. (2)Its storage temperature range would be from -65°C to 150°C. (3)Its voltage on EA/Vpp pin to Vss would be from 0V to +13V. (4)Its voltage on any other pin to Vss would be from -0.5V to +6.5V. (5)Its Iol per I/O pin would be 15mA. (6)Its power dissipation would be 1.5W (based on package heat transfer limitations, not device power consumption). (7)Its typical junction temperature would be +135°C (based upon ambient temperature at +125°C). It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some AN80C51BH electrical characteristics are concluded as follow. (1)Its input low voltage except EA would be min -0.5V and max 0.2Vcc-0.25V. (2)Its input low voltage to EA would be min 0V and max 0.2Vcc-0.45V. (3)Its input high voltage except XTAL1, RST would be min 0.2Vcc+1.0V and max Vcc+0.5V. (4)Its input high voltage XTAL1, RST would be min 0.7Vcc+0.1V and max Vcc+0.5V. And so on. If you have any question or suggestion or want to know more information please contact us for details.
