GENERAL DESCRIPTION
The W78E052C is an 8-bit microcontroller which can accommodate a wider frequency range with low power consumption. The instruction set for the W78E052C is fully compatible with the standard 8051. The W78E052C contains an 8K bytes Flash EPROM; a 256 bytes RAM; four 8-bit bi-directional and bit-addressable I/O ports; an additional 4-bit I/O port P4; three 16-bit timer/counters; a hardware watchdog timer and a serial port. These peripherals are supported by eight sources two-level interrupt capability. To facilitate programming and verification, the Flash EPROM inside the W78E052C allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security.
The W78E052C microcontroller has two power reduction modes, idle mode and power-down mode, both of which are software selectable. The idle mode turns off the processor clock but allows for continued peripheral operation. The power-down mode stops the crystal oscillator for minimum power consumption. The external clock can be stopped at any time and in any state without affecting the processor.

GENERAL DESCRIPTION
The W77E532A is a fast 8051 compatible microcontroller with a redesigned processor core without wasted clock and memory cycles. As a result, it executes every 8051 instruction faster than the original 8051 for the same crystal speed.
Typically, the instruction executing time of W77E532A is 1.5 to 3 times faster then that of traditional 8051, depending on the type of instruction. In general, the overall performance is about 2.5 times better than the original for the same crystal speed.
Giving the same throughput with lower clock speed, power consumption has been improved. Consequently, the W77E532A is a fully static CMOS design; it can also be operated at a lower crystal clock.
The W77E532A contains In-System Programmable(ISP) 128 KB bank-addressed Flash EPROM; 4KB auxiliary Flash EPROM for loader program; operating voltage from 4.5V to 5.5V; on-chip 1 KB MOVX SRAM; three power saving modes.

GENERAL DESCRIPTION
 W9864G6IH is a high-speed synchronous dynamic random access memory (SDRAM), organized as 1M words × 4 banks × 16 bits.
W9864G6IH delivers a data bandwidth of up to 200M words per second.
For different application, W9864G6IH is sorted into the following speed grades: -5, -6, -7/-7S. The -5 parts can run up to 200MHz/CL3.
The -6 parts can run up to 166MHz/CL3.
The -7/-7S parts can run up to 143MHz/CL3.
And the grade of -7S with tRP = 18nS.
Accesses to the SDRAM are burst oriented.
Consecutive memory location in one page can be
accessed at a burst length of 1, 2, 4, 8 or full page when a bank and row is selected by an ACTIVE command.
Column addresses are automatically generated by the SDRAM internal counter in burst operation.
Random column read is also possible by providing its address at each clock cycle.
The multiple bank nature enables interleaving among internal banks to hide the precharging time.
By having a programmable Mode Register, the system can change burst length, latency cycle, interleave or sequential burst to maximize its performance.
W9864G6IH is ideal for main memory in high performance applications.
