Description The HITACHI HM5116100 is a CMOS dynamic RAM organized 16,777,216-word × 1-bit. It employs the most advanced 0.5µm CMOS technology for high performance and low power. The HM5116100 offers Fast Page Mode as a high speed access mode. It is packaged in 26-pin plastic SOJ.
Features • Single 5 V (±10%) • Access time: 60 ns/70 ns (max) • Power dissipation - Active mode: 440 mW/385 mW (max) - Standby mode 11 mW (max) • Fast page mode capability • Refresh cycles - 4096 refresh cycles : 64 ms • 3 variations of refresh - RAS-only refresh - CAS-before-RAS refresh - Hidden refresh • Test function - 16-bit parallel test mode
This device presents 4-to-16 line decoder with latched inputs. The HD74HC4515 presents a low level at the selected output. This device consists of four storage latches with common strobe and inhibit (G) inputs. When a low signal is applied to the strobe input, the input data is stored, decoded, and presented to the output. When inhibit is high, all HD74HC4515 outputs are a high logic level.
The HITACHI HA11225 is an FM IF Amplifier and Detector developed for HI FI Tuners. This IC is encapsulated in DIP-16 pin.
■ FUNCTIONS ● FM IF Amplifier ● Quadrature Detector ● Audio Amplifier ● Muting Circuit ● AFC, Tuning Meter Driver ● AGC Control Voltage Generator ● Muting Control Voltage Generator ● Signal Meter Driver
Overview Features The H8/532 is an original HITACHI CMOS microcomputer unit (MCU) comprising a highperformance CPU core plus a full range of supporting functions—an entire system integrated onto a single chip.
The CPU features a highly orthogonal instruction set that permits addressing modes and data sizes to be specified independently in each instruction. An internal 16-bit architecture and 16-bit access to on-chip memory enhance the CPU’s data-processing capability and provide the speed needed for realtime control applications.
The on-chip supporting functions include RAM, ROM, timers, a serial communication interface (SCI), A/D conversion, and I/O ports. An on-chip data transfer controller (DTC) can transfer data in either direction between memory and I/O independently of the CPU.
For the on-chip ROM, a choice is offered between masked ROM and programmable ROM (PROM). The PROM version can be programmed by the user with a general-purpose PROM writer.
