4-BIT, SINGLE-CHIP CMOS MICROCOMPUTERS WITH COMPARATOR

Description The μPD7556/66A and μPD7566/66A are low-end versions of μPD7500 series products. These microcomputers incorporated a 4-bit comparator input and are useful as slave CPUs to high-end μPD7500 series or 8-bit μCOM-87 series products. Features

MOS INTEGRATED CIRCUIT

FEATURES • 45 instructions (subset of the mPD7500H SET B) • Instruction cycle: 2.86 microseconds (700 kHz, at 5V) with ceramic oscillator • Program memory (ROM): 1,024 words x 8 bits • Data memory (RAM): 64 words x 4 bits • Test sources: 1 external and 1 internal • 8-bit timer/event counter

DC-DC CONVERTER BOOST(STEP-UP) 1.2MHz, MICROPOWER SYNCHRONOUS

DESCRIPTION The A7566 is synchronous, fixed frequency, step-up DC/DC converters delivering high efficiency in a 6- lead SOT package. Capable of supplying 3.3V at 100mA from a single AA cell input, the device contain an internal NMOS switch and PMOS synchronous rectifier. A switching frequency of
