Microprocessor
Datasheet
The TinyRISC LR4102 Microprocessor is a compact, high performance
32-bit microprocessor implemented in the LSI Logic G11 technology.
The LR4102 is a complete microprocessor solution with caches, an
external bus interface with built-in memory controllers, and on-chip
debug. The LR4102 is built using the EZ4102 EasyMACRO subsystem,
available to customers through the LSI Logic CoreWare
program.
The LR4102 provides a 32-bit FBusMACRO to control all off-chip data
transactions (including DRAM or SDRAM) and an EJTAG interface for
on-chip debug with PC trace output.

LR4102 Block Diagram
The LR4102 microprocessor is powered by either 2.5 V (for 85 MHz
operation) or 1.8 V (for 50 MHz operation). The chip I/O ring requires
3.3 V. With a system clock of 85 MHz, peak performance is 85 MIPS and
sustained performance is estimated at 68 MIPS. With a 50 MHz clock,
performance is 50 MIPS peak and 40 MIPS sustained.
