Description
The AT8xEB5114 is a high performance version of the 80C51 8-bit microcontroller in a
Low Pin Count package.
The
AT8xEB5114 retains all the features of the standard 80C51 with 4 Kbytes pro-
gram memory, 256 bytes of internal RAM, a 7-source, 4-level interrupt system, an on-
chip oscillator and two timers/counters. AT8xEB5114 may include a serial two wire
interface EEPROM housed together with the microcontroller die in the same package.
The AT8xEB5114 is dedicated for analog interfacing applications. For this, it has a 10-
bit, 6 channels A/D converter and two PWM units; these PWM blocks provide PWM
generation with variable frequency and pulse width.
In addition, the AT8xEB5114 has a Hardware Watchdog Timer and an X2 speed
improvement mechanism. The X2 feature allows to keep the same CPU power at a
divided by two oscillator frequency. The prescaler allows to decrease CPU and periph-
erals clock frequency. The fully static design of the AT8xEB5114 allows to reduce
system power consumption by bringing the clock frequency down to any value, even
DC, without loss of data.
