About this manual

The document details the in-circuit programming feature for ST62 devices, allowing the programming or reading of non-volatile memory (EPROM or EEPROM) without removing the device from its application board. This process utilizes a 16-pin connector to connect the application board to a programming tool, simplifying handling for complex packages like PQFP.

Frequently asked questions

What is the maximum load current allowed when supplying the application board through connector pins?

The total load current must not exceed 100mA.

What is the minimum resistor value required for Vpp/TM on the application board?

It should be pulled down by a resistor with a minimum value of 10 Kohms.

What capacitor is mandatory to add between Vpp/TM and Vss?

A 100nF ceramic capacitor must be added.
