S3C44B0X datasheet

 

Description

SAMSUNG’s S3C44B0X 16/32-bit RISC microprocessor is designed to provide a cost-effective and high performance micro-controller solution for hand-held devices and general applications. To reduce total system cost, S3C44B0X also provides the following: 8KB cache, optional internal SRAM, LCD controller, 2-channel UART with handshake, 4-channel DMA, System manager (chip select logic, FP/ EDO/SDRAM controller), 5-channel timers with PWM, I/O ports, RTC, 8-channel 10-bit ADC, IIC-BUS interface, IIS-BUS interface, Sync. SIO interface and PLL for clock.

The device was developed using a ARM7TDMI core, 0.25 um CMOS standard cells, and a memory compiler. Its low-power, simple, elegant and fully static design is particularly suitable for cost-sensitive and power sensitive applications. Also S3C44B0X adopts a new bus architecture, SAMBA II (SAMSUNG ARM CPU embedded Microcontroller Bus Architecture).

Features

1. 2.5V Static ARM7TDMI CPU core with 8KB cache . (SAMBA II bus architecture up to 66MHz)

2. External memory controller. (FP/EDO/SDRAM Control, Chip Select logic)

3. LCD controller (up to 256 color DSTN) with 1-ch LCD-dedicated DMA.

4. 2-ch general DMAs / 2-ch peripheral DMAs with external request pins

5. 2-ch UART with handshake(IrDA1.0, 16-byte FIFO) / 1-ch SIO

6. 1-ch multi-master IIC-BUS controller

7. 1-ch IIS-BUS controller

8. 5-ch PWM timers & 1-ch internal timer

MAX809L Datasheet PDF – Microprocessor Supervisory

Part Number: MAX809L

Function: 3-Pin Microprocessor Reset Circuits

Package: SC70-3, SOT23-3 Type

Manufacturer: Maxim Integrated

Pinouts:

MAX809L datasheet

 

Description

The MAX803, MAX809L, MAX810 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external compo nents and adjustments when used with +5V, +3.3V, +3.0V, or +2.5V powered circuits.

These circuits perform a single function: they assert a reset signal whenever the VCCsupply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCChas risen above the reset thresh old. Reset thresholds suitable for operation with a variety of supply voltages are available.

Features

1. Fully Specified Over Temperature

2. 140ms min Power-On Reset Pulse Width

3. Power Supply Transient Immunity
