The µPD178004A, 178006A, 178016A, and 178018A are 8-bit single-chip CMOS microcontrollers that incorporate hardware for digital tuning systems. The CPU uses the 78K/0 architecture, which makes it easy to implement high-speed access to internal memory and control of peripheral hardware. The instructions used are the high-speed 78K/0 instructions, suitable for system control. The rich assortment of peripheral hardware includes an input/output port, 8-bit timer, A/D converter, serial interface, power-ON clear circuits, as well as a pre-scaler for digital tuning, a PLL frequency synthesizer, and a frequency counter. The µPD178P018A, one-time PROM or EPROM versions which can be operated in the same supply voltage range as for the mask ROM versions, and various development tools, are also available.

µPD17072 and 17073 are low-voltage 4-bit single-chip CMOS microcontrollers containing hardware ideal for organizing a digital tuning system. The CPU employs 17K architecture and can manipulate the data memory directly, perform arithmetic operations, and control peripheral hardware with a single instruction. All the instructions are 16-bit one-word instructions. As peripheral hardware, a prescaler that can operate at up to 230 MHz for a digital tuning system, a PLL frequency synthesizer, and an intermediate frequency (IF) counter are integrated in addition to I/O ports, an LCD controller/driver, A/D converter, and BEEP. Therefore, a high-performance, multi-function digital tuning system can be configured with a single chip of µPD17072 or 17073. Because the µPD17072 and 17073 can operate at low voltage (VDD = 1.8 to 3.6 V), they are ideal for controlling battery-cell driven portable devices such as portable radio equipment, headphone stereos, or radio cassette recorders.

The µPD17071GB-012 is a CMOS microcontroller with an on-chip PLL frequency synthesizer for receiving international FM and AM and Japanese TV broadcasting. In addition, because it includes a prescaler (230 MHz MAX.), IF counter, and LCD controller/driver, it constitutes a high-performance, multi-function FM, AM, or TV tuner on a single chip.

The PD16855A/B/C/D is a dual high-side switch from NEC for use on the power supply bus of the Universal-Serial-Bus (USB). It features two Pch power MOSFETs in the switch part, each with low on resistance (100 mΩ TYP.), as well as over current detection, thermal shutdown and under voltage lockout circuits. The over-current-detect result can be reported to the controller by flag-pin.

This is a low capacitance type diode developed by NEC for E.S.D. (Electrostatic Discharge) protection. This product series is the most suitable for the ESD protection in the high-speed data communication bus such as USB. With four elements mounted in the 5-PIN Mini Mold Package, that product can cope with high density assembling.

This product is a member of the µPD780034AY series and is a µPD780034A subseries product with an added multimaster-supporting I2C bus interface, and is suitable for AV equipment applications.

The µPD7564A is a 4-bit single-chip microcomputer with a small number of ports in a small package, which is of low-order models, µPD7554 and 7564 sub-series in the µPD7500 series. With an on-chip serial interface, it per- forms efficient dispersion processing of a system as a sub-CPU for the 75X series or 78k series. The µPD7564A has outputs to directly drive a triac and LEDs and allows selection among many types of input/ output circuits using their respective mask options, sharply reducing the number of external circuits required.

MC-4564EC727 64M-WORD BY 72-BIT SYNCHRONOUS DYNAMIC RAM MODULE REGISTERED TYPE is a memory module produced by NEC Corporation. The module supports 36 128M SDRAM and can provide high-density and large amounts of memory in a small space.
