5. Winbond W79E659 MCU 

The W79E659 is a fast, 8051/52-compatible microcontroller with a redesigned processor core that 
eliminates wasted clock and memory cycles. Typically, the W79E659 executes instructions 1.5 to 3 
times faster than that of the traditional 8051/52, depending on the type of instruction, and the overall 
performance is about 2.5 times better at the same crystal speed. As a result, with the fully-static 
CMOS design, the W79E659 can accomplish the same throughput with a lower clock speed, reducing 
power consumption. The W79E659 provides 256 bytes of on-chip RAM; 1-KB of auxiliary RAM; seven 
8-bit, bi-directional and bit-addressable I/O ports; an additional 4-bit port P4; three 16-bit 
timer/counters; an UART serial port, 2 channels of I2C with master/slave capability and 8 channels of 
10-bit ADC. These peripherals are all supported by ten interrupt sources with 2 levels of priority. The 
W79E659 contains a 32-KB Flash EPROM whose contents may be updated in-system by a loader 
program stored in an auxiliary, 4-KB Flash EPROM. Once the contents are confirmed, it can be 
protected for security. 
 

6. Fintek F75101R GPIO Expander 

The F75101R is a multifunctional general purpose IO chip providing 16 GPIO powered by 3VSB by 
power on setting. Level or pulse modes can be programmed by registers. With 2 sets of watchdog 
timer, F75101R provides more flexible control for system. 
 

7. Eon EN29F040A 4MBit Flash 

The EN29F040A is a 4-Megabit, electrically erasable, ead / write non-volatile flash memory. organized 
into 512K ords with 8 bits per word, the 4M of memory is arranged in eight uniform sectors of 
64Kbytes each. Any byte can be programmed typically in 10

μ

s. The EN29F040A features 5.0V 

voltage read and write operation, with access times as fast as 45ns to eliminate the need for WAIT 
states in high-performance microprocessor systems. 
 

8. YAMAHA YDA138 Audio Amplifier 

YDA138 (D-3) is a high efficient digital audio power amplifier IC that operates with a single 12V power 
supply. An audio power amplifier with a maximum output of 10W (RL=8 ) 2ch can be configured with 
one chip. YDA138 has a “Pure Pulse Direct Speaker Drive Circuit” which directly drives speakers 
while reducing distortion of pulse output signal and reducing noise on the signal, and realizes the 
highest standard low distortion rate characteristics and low noise characteristics as 10W-class of 
output digital amplifier IC. In addition, circuit design with fewer external parts can be made depend on 
the condition of use because corresponds to filter less. YDA138 provides Overcurrent protection 
function for speaker output terminals, IC thermal protection function, POP noise reduction function, 
and AM interference measures function as well as power-down function and output mute function. 
 

9. Sipex SP3243 RS-232 transceiver 

The SP3243 transceivers meet the EIA/TIA-232 and ITU-T V.28/V.24 communication protocols. 
generate 5.5V RS-232 voltage levels from a 3.0V to +5.5V power supply and operate at a data 
rate of 120kbps fully loaded. The SP3243 devices feature 

ٛ

 circuitry automatically wakes up from . It 

occurs after a RS-232 cable being disconnected. Under this condition, the internal charge pump and 
the drivers will be shut down. Otherwise, the system automatically comes online.   
 

10. Mitsumi MM1671 Low Supply Voltage 75 Ohm Driver 

This IC is a 75

ȍ

 driver with a built-in LPF that can operate at low voltage. It supports 3V and 5V 

operating power voltage, and is ideal for video signal output in devices ranging from portable digital 
still cameras to stationary equipment such as DVD players. It incorporates a high performance 
4-stage LPF, which is ideal for removing DAC sampling noise. In addition, ultra-low current 
consumption has been achieved b of the batteries in portable devices. The built-in amp gain on this IC 
is available in series: 6dB/9dB/12dB/16.5dB, thus enabling support for DAC and a variety of output 
amplitudes. There is also a series with input clamp and one without, allowing support for a range of 
video signals, not just composite signals. 
 

11. EtronTech EM636165TS-5G SDRAM 

The EM636165 SDRAM is a high-speed CMOS synchronous DRAM containing 16 Mbits. It is
