PIC16F876A-I/SP
PIC16F873A/876A devices are available only in 28-pin
packages, while PIC16F874A/877A devices are available in 40-pin and 44-pin packages. All devices in the
PIC16F87XA family share common architecture with
the following differences:
? The PIC16F873A and PIC16F874A have one-half
of the total on-chip memory of the PIC16F876A
and PIC16F877A
? The 28-pin devices have three I/O ports, while the
40/44-pin devices have five
? The 28-pin devices have fourteen interrupts, while
the 40/44-pin devices have fifteen
? The 28-pin devices have five A/D input channels,
while the 40/44-pin devices have eight
? The Parallel Slave Port is implemented only on
the 40/44-pin devices
Pic16f877 I/Pt
The PIC16F873, PIC16F874, PIC16F876 and PIC16F877 are the four covered devices. Devices for the PIC16F876/873 and PIC16F877/874 available in 28-pin and 40-pin packages, respectively. On 28-pin devices, the Parallel Slave Port is not implemented. Each PIC16F87X device has the ability to access an 8K word block of program memory continuously. Only 11 bits of address are provided by the CALL and GOTO instructions, allowing branching inside any 2K program memory page. PCLATH4:3> provides the upper 2 bits of the address when performing a CALL or GOTO instruction. The user must make sure that the page choose bits are set when performing a CALL or GOTO instruction in order for the chosen programme memory page to be addressed. The full 13-bit PC is popped off the stack whenever a return from a CALL instruction (or interrupt) is performed. Therefore, the return instructions do not need the modification of the PCLATH4:3> bits (which POPs the address from the stack).
Data Memory Organization
The General Purpose Registers and Special Function Registers are divided up into several banks in the data memory. The bank select bits are bits RP1 (Status:6) and RP0 (Status:5). Each bank stretches to 7Fh (128 bytes). The Special Function Registers are only permitted in the bottom positions of each bank. General Purpose Registers, which are implemented as static RAM, are located above the Special Function Registers. Special Function Registers are present in all installed banks. For code reduction and faster access, some commonly used Special Function Registers from one bank may be duplicated in another bank.
PIC16F877A Microcontroller
PIC16F877A is the most commonly used entry-level?8-bit PIC Microcontroller. It is a 40-pin 8-bit Microcontroller with 14kB of program memory. It does not have an internal oscillator but can work up to 20MHz with external oscillators. The controller has 8 ADC channels with 10-bit resolution and also supports PWM on 2 pins. It has two 8-bit timers and one 16-bit timer and supports communication protocols like UART, SPI, and IIC. You can also check other?PIC microcontroller?Components.
