8051 Microcontroller Introduction and Basics - Electronics Hub
WEBMar 24, 2024 · The total external memory that an 8051 Microcontroller can access for RAM and ROM is 64KB (216 for each type). Additional Features: Interrupts, on-chip oscillator, Boolean Processor, Power Down Mode, etc. NOTE: Some of the features like size of RAM and ROM, number of Timers, etc. are not generic.
Registers in 8051 Microcontroller - Electronics for You
WEBJun 3, 2023 · Microcontroller 8051 has two timer/counters namely timer 0 and timer 1. Size of each timer is 16 bits wide. Since the architecture of 8051 is 8 bits, the timers are separated into two 8-bit registers. The timer 0 is divided into low byte of timer 0 (TL0) and high byte of timer 0 (TH0). Same way timer 1 as TL1 and TH1.
