LGT8F88A FLASH Microcontroller

lgt8f88a_arch6

LGT8F88A based on LGT8XM, a deeply optimized 8bit RISC core. In order to maximize performance and parallelism, LGT8XM uses Harvard architecture – with separate memories and buses for program and data. Instructions are executed inside a 2-stage pipeline. 2-stage pipeline reduces useless fetch-stage, so decrease power consumption caused by flash memory. LGT8XM introduce a smart instruction cache, which can fetch more instructions one time, effectively decrease memory accessing operations. Based on our test, LGT8XM decrease about 40% power consumption caused by program memory compare to other 8bit architectures.
