STEVAL-IPE005V1, STPM01 programmer board - hardware

IntroductionThe 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 checklistThe STPM01 kit package includes the following items:

● The STPM01 board

● A CD-ROM with software and documentation

2.2 DebugSoftware debug is via a standard 20-pin JTAG connection.

2.3 ResetThe reset sources are:

● Power-on reset

● Push-button reset

● JTAG reset from an in-circuit emulator

2.4 Power suppliesPower 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-232A 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 connectorA 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.
