STEVAL-IPE005V1, STPM01 programmer board - hardware
Introduction
The STPM01 - programmer kit works in conjunction with the STPM01 energy meter ASSP
device and with the STPM01 manager software. It is an integrated system designed to
provide the user with a complete, ready-to-use energy meter application. The reference
design is a high-end solution for power metering based on the STR710 microcontroller with
an embedded RTC and an external memory interface (EMI) ready to drive 1Mbyte of on-
board SRAM.
The kit also integrates an on-board optical insulated serial line allowing isolation of the
board ground reference in order to avoid propagation of overvoltage on the PC side.
Moreover, the on-board charge pump allows burning the STPM01 energy meter ASSP
device registers.
Access to the STPM01 device registers is ensured using a dedicated SPI bus interface.
The STPM01 programmer kit demonstrates how effectively the STPM01 can be used in
real-world energy meter applications and it helps the user to develop his own application.
The STPM01 programmer kit can be used in two ways:
■For demonstration purposes, by connecting the reference design to an AC power source
and changing all the settings parameters through the GUI interface and the hardware
programmer/reader board
■To evaluate and develop a custom application

2 STPM01 kit components
2.1 Package checklist
The STPM01 kit package includes the following items:
●The STPM01 board
●A CD-ROM with software and documentation
2.2 Debug
Software debug is via a standard 20-pin JTAG connection.
2.3 Reset
The reset sources are:
●Power-on reset
●Push-button reset
●JTAG reset from an in-circuit emulator
2.4 Power supplies
Power to the board is supplied using a lump in cord power supply providing 5 V to the board.
All other required voltages are provided by on-board voltage regulators or voltage
convectors.
An isolated 5 V DC/DC provides the isolated voltage supply for the opto-coupler devices.
2.5 Opto-isolated RS-232
A general-purpose, asynchronous serial I/O data port is connected through 9-pin D-type
male connectors. The port is opto-isolated in order to avoid overvoltage on the PC side.
2.6 SPI connector
A devoted SPI connector allows interfacing the STPM01 device. It provides all the SPI
signals required to communicate with the STPM01 interface registers. Moreover it provides
a 24 V line which allows burning the STPM01 configuration registers.
