Advanced Products - MBL8049N/E/H MBL8039N/E/H NMOS Single-Chip a-Bit Microputer FUJITSU October 1986 Edition 1.0 Description The Fujitsu MBL8049/MBL8039 is a totally self-contained 8-bit parallel one-chip microputer fabricated with an N-channel silicon gate Ma S process. The MBL8049 has a 2K x 8 ROM program memory, a 128 x 8 RAM data memory, 27 I/O ports, an 8-bit timer/counter and clock generator on chip. A single power supply of +5V is used. The MBL8039 is identical to the MBL8049 except without program memory. It can be used with external memory for system prototyping and preproduction systems. The design is optimized for low cost, high performance applications because the MBL8049/MBL8039 is fabricated on a single silicon chip and can be used for applications that require additional expansion of ROMs, RAMs, I/O port, etc. This microputer permits external program operation and a single-step operation mode. Low power applications are possible by using the stand-by mode feature . The MBL8049/MBL8039 is packaged in a standard 40-pin DIP package and operation is guaranteed from O'C to 70'C.
