OVERVIEW

Samsung S3C380D 16/32-bit RISC microcontroller is a cost-effective and high-performance microcontroller
solution for TV applications.

Among the outstanding features of the S3C380D is its CPU core, a 16/32-bit RISC processor (ARM7TDMI)
designed by Advanced RISC Machines, Ltd. The ARM7TDMI core is a low-power, general-purpose
microprocessor macro-cell that was developed for use in application-specific and customer-specific integrated
circuits. Its simple, elegant, and fully static design is particularly suitable for cost-sensitive and power-sensitive
applications.

The S3C380D was developed using the ARM7TDMI core, CMOS standard cell, and a data path compiler. Most
of the on-chip function blocks were designed using an HDL synthesizer. The S3C380D has been fully verified in
the Samsung ASIC test environment.

By providing a complete set of common system peripherals, the S3C380D minimizes overall system costs and
eliminates the need to configure additional components.

The integrated on-chip functions that are described in this document include:

• 4-Kbyte RAM (3008-byte (1504 × 16 bits) general register and 1088-byte (544 × 16 bits) OSD/CCD RAM)

• 128-Kbyte internal program memory

• Two 14-bit PWM modules

• Three 16-bit timers

• On screen display module

• Crystal/Ceramic oscillator or external clock can be used as the clock source

• Standby mode support: SLEEP mode

• One 8-bit basic timer and 3-bit watchdog timer

• Interrupt controller (16 interrupt sources and 2 vectors)

• Five 4-bit ADCs

• Four programmable I/O ports

• 42-pin SDIP
