HD64F2134FA20VTR

Product Summary

The HD64F2134FA20VTR has 4 k bytes of on-chip high-speed static RAM. The on-chip RAM is connected to the CPU by a 16-bit data bus, enabling both byte data and word data to be accessed in one state. This makes it possible to perform fast word data transfer. The on-chip RAM can be enabled or disabled by means of the RAM enable bit (RAME) in the system control register (SYSCR). The HD64F2134FA20VTR has 128 kbytes of on-chip ROM. The ROM is connected to the CPU by a 16-bit data bus. The CPU accesses both byte and word data in one state, enabling faster instruction fetches and higher processing speed. The mode pins (MD1 and MD0) and the EXPE bit in MDCR can be set to enable or disable the on-chip ROM. The lineups for the HD64F2134FA20VTR include flash memory versions which can be erased and programmed on-board as well as by a general-purpose PROM programmer.
