80515 MPU Core
80515 Overview
The 71M6513/6513H includes an 80515 MPU (8-bit, 8051-compatible) that processes most instructions in one clock cycle.
Using a 5MHz clock results in a processing throughput of 5 MIPS. The 80515 architecture eliminates redundant bus states and
implements parallel execution of fetch and execution phases. Normally a machine cycle is aligned with a memory fetch, there-
fore, most of the 1-byte instructions are performed in a single cycle. This leads to an 8x performance (in average)
improvement (in terms of MIPS) over the Intel 8051 device running at the same clock frequency.
Actual processor clocking speed can be adjusted to the total processing demand of the application (metering calculations,
AMR management, memory management, LCD driver management and I/O management) using the I/O RAM register
MPU_DIV[2:0].
Typical measurement and metering functions based on the results provided by the internal 32-bit compute engine (CE) are
available for the MPU as part of Teridian’s standard library. A standard ANSI “C” 80515-application programming interface
library is available to help reduce design cycle.
Memory Organization
The 80515 MPU core incorporates the Harvard architecture with separate code and data spaces.
Memory organization in the 80515 is similar to that of the industry standard 8051. There are three memory areas: Program
memory (flash), external data memory (XRAM), physically consisting of XRAM, CE DRAM, CE PRAM and I/O RAM, and
internal data memory (Internal RAM). Figure 6 shows the memory map (see also Table 54).
Internal and External Data Memory: Both internal and external data memory are physically located on the 71M6513 IC. Ex-
ternal data memory is only external to the 80515 MPU core.

Figure 6: Memory Map
Program Memory: The 80515 can address up to 64KB of program memory space from 0x0000 to 0xFFFF. Program memory
is read when the MPU fetches instructions or performs a MOVC operation.
After reset, the MPU starts program execution from location 0x0000. The lower part of the program memory includes reset and
interrupt vectors. The interrupt vectors are spaced at 8-byte intervals, starting from 0x0003.
External Data Memory: While the 80515 can address up to 64KB of external data memory in the space from 0x0000 to
0xFFFF, only the memory ranges shown in Figure 6 contain physical memory. The 80515 writes into external data memory
