Description

The 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 program memory, 256 bytes of internal RAM, 7-source, 4-level interrupt system, an onchip 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 10bit, 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 peripherals 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.

The AT8xEB5114 has 3 software-selectable modes of reduced activity for further reduction in power consumption. In idle mode the CPU is frozen while the peripherals are still operating. In quiet mode, only the A/D converter is operating. In power-down mode the RAM is saved and all other functions are inoperative. Three oscillator sources, crystal, precision RC and low power RC, provide versatile power management. The AT8xEB5114 is available in low pin count packages (ROM and flash versions). Figure 1.
