Microcontroller Timing Characteristics

Overview

The following tables detail the result of laboratory programming trials for various

microcontrollers. All test performed used the ‘In-System Programming (ISP) mode. These

timings and settings are meant for guidance only. E&OE. Results may differ depending on

microcontroller revision, PC, power supply, target system etc.

Definitions:

Voltage - Supply voltage to programmer and target device

Fosc - Frequency of target microcontroller oscillator

Code time - Time taken to program the target device CODE area with random data

All measurements were taken with the following equipment:

Software : Gemini V0.24

PC : DX2-50

Programmer : GEMINI-1

Operating System : Windows 95

Target communication speed: Variable

Programming Mode : ISP

Vcc : +5.0V

WARNING

High currents are drawn by the GEMINI-1 programmer during erasing & writing. Care must

be taken to ensure the target power supply can supply the necessary inrush current.
