FAQ
Question：Do flash programmers need regular calibration?
Since the flash programmer is not a measuring instrument that requires accuracy, regular calibration is not required.
A flash programmer is a device that sends and receives commands and data via serial communication with the microcomputer on the target board, and program data to the flash memory built into the microcomputer.
The rating of the input high level voltage (VIH) on the microcomputer is generally about min 0.7 VDD to 0.8 VDD.
For example, if the VIH (min) of the microcomputer is 0.8 VDD and the operating voltage is 5.0V, the allowable lower limit of the High level voltage is 4.0V, so voltage level accuracy is not required. In addition, it is possible that the voltage may drop due to the influence of the circuit (for example, pull-down resistor) on the target board to which the connection is made or the wiring routing, so it does not make much sense for the flash programmer to seek accuracy.
