LM7001 FM Transmitter

LM7001 FM Transmitter that will be created using Atmega8 controllers and use the Display Nokia 3310,

and the code is created using BASCOM-AVR. for FM oscillator using FET transistor 2SK192A.

The first and second buffer FM transmitter using transistor 2SC2026. Drivers using a transistor 2SC2053. 

Final use 2SC1947 Transistor.

LM7001 and LM7000 have the same internal registers. so you can use LM7000 for this project. and incidentally we use LM7000 as Component testing. LM7000 is not so popular, the difference lies in the number of pins.

LM7000 has 20 pins, and the LM7001 has a 16 pin

 

for a LM7000 or LM7001 simulation software we use Proteus. The following schematic controllers

 

Programming LM7000 or LM7001:

LM7000 / LM7001 is controlled using a protocol 3 wires. each Data, Clock (CL), and Chip Enable (CE). the figure below shows the timing Programming LM7000 / LM7001.

 

to begin programming the CE pin must be logic high, and then prepare Data. The next step is activated Clock (CL).

for the calculation of frequency using the following formula:
