TinyRISC® LR4102 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. Figure 1 illustrates the LR4102 chip. Figure 1 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.
