71M651X Energy Meter IC A Maxim Integrated Products Brand APPLICATION NOTE AN_651X_033 NOVEMBER 2010 Development Tools This Application Note describes the various development and programming tools available for the 71M651X, 71M652X, and 71M653X families of Energy Meter ICs. Compiler Teridian recommends using the CA51 “Compiler Kit” by Keil (www.keil.com), which contains the µVision 3 Integrated Development Environment (IDE), complete with 8051 assembler, editor, C compiler, linker, and locator. The Demo Code shipped with the Demo Kits for Teridian Energy Meter ICs is written using this tool. Keil offers the best support for the memory model of the 80515 core used in the 71M651X ICs. It is possible to use alternative compilers, but the code for these is not supported by Teridian. Figure 1: Keil µVision3 User Interface While all Demo Code is written using the standard CA51 tool by Keil, significant improvements in memory usage can be made by using the PK51 “Professional Developer’s Kit” by Keil. The PK51 contains the LX51 advanced linker that can reduce code size by up to 8%, using special optimization techniques. Teridian Application Note 1/8 AN_651X_033 Development Tools In-Circuit Emulator (ICE) The Signum Systems ADM51 (www.signum.com) is compatible with the Keil symbolic output format and supports the 71M65XX ICs, including the 71M653X bank switching mechanism. It is useful to perform the following tasks: • • • Code emulation with breakpoints, watch windows, etc., with support of source code symbols Memory monitoring and manipulation (SFRs, XRAM, I/O RAM) Flash erase and code loading into flash memory of the 71M651X Teridian supplies the ADM51 to customers at a preferred price (P/N DB6510-ADM51). Note: Since meters are sometimes tested with live voltages, isolation of the emulator is strongly recommended. USB isolators are available from various vendors. For example, the UISOHUB4 or UEF10M are available at B&B Electronics (www.bb-elec.com, or http://www.bb-europe.com/). Figure 2: Signum ADM51 Emulator Pod Emulators are available from Signum Systems that support trace memory. Trace memory can only be used with the 71M6513 and 71M6513H ICs. Signum offers the following emulators with enhanced features: • • ADM51-Trace: Records PC, SFR, IRAM and XDATA transactions in real-time on devices with trace port (6513, 6534) ADM51-Trace-CE: Same as above, but with added complex events triggering Teridian Application Note 2/8 AN_651X_033 Development Tools Figure 3: Signum WEMU51 User Interface Teridian Application Note 3/8 AN_651X_033 Development Tools Flash Programmer The Signum ADM51 can serve as a programmer for prototyping and small quantities. For programming production quantities, Teridian offers the TFP2 Flash Programming Module (P/N 80515-FPBM-TFP2), which is a stand-alone programmer that can be operated manually or in an ATE environment (see Figure 4). Figure 4: Teridian TFP-2 Flash Programmer The TFP2 offers the following features: • • • • • • Stand-alone or PC-controlled programming Variable flash memory size selectable LEDs and signal outputs for PASS and FAIL Pushbutton and digital control inputs compatible with ATE Can erase and re-program ICs that have the SECURE bit set Controls ICE_E for 71M652X and 71M653X ICs Teridian Application Note 4/8 AN_651X_033 Development Tools Gang Programmers and Production Programmers Single and gang programmers for lab quantities as well as high-volume programmers providing device handlers and feeders are available from BPM Microsystems (www.bpmmicro.com). Discontinued Devices The gang programmer that was available from Teridian has been discontinued. All production programming should be based on the devices available at BPM Microsystems (Houston, TX, USA). Teridian Application Note 5/8 AN_651X_033 Development Tools Software/Firmware The complete set of sources for the MPU Demo Code is available to the customer as well as images of CE code and CE data. The source modules can be combined to quickly implement a working meter. Software development is supported by documentation in form of a Software User's Guide (SUG). The SUG contains: • • • • • • HW and SW requirements Description of SW utilities Command line interface description Tool installation guide Demo Code description 80515 Core Reference Demo Boards and Demo Kits Demo Kits are the quickest way to get familiar with the Teridian 71M65XX family of energy metering ICs. They are very useful to evaluate the performance of the ICs without having to write any software, and they can serve as a prototyping platform for software development. Each Demo Kit contains the following: 1) One Teridian energy metering IC on a Demo Board implementing a pre-programmed demonstration meter, complete with resistor dividers, connectors for voltage and current sensor inputs, EEPROM, pulse LEDs, AC power supply, DC power supply and LCD display. In addition, various test points, configuration headers and access to the emulator interface of the IC are provided. 2) Debug Board. This board provides isolation and translation to RS-232 voltage levels. It enables the user to control various parameters of the Demo Board via a simple serial command line interface. 3) Two power supplies (for Demo Board and Debug Board). 4) Serial cable for connection of the Debug Board to a terminal or PC (COM port). 5) CD-ROM with documentation (Data Sheet, User’s Manual, Software User’s Guide), Demo Code (executable files and source files), and various utilities. Figure 5: 71M6513 Demo Board with Debug Board After the evaluation phase, the Demo Board can serve as a platform for code development, which can be done simultaneously with schematic design and layout.
