Description

Samsung S3F380D 16/32-bit RISC microcontroller is a cost-effective and high-performance microcontroller solution for TV applications.

Among the outstanding features of the S3F380D 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. IS3F380D's simple, elegant, and fully static design is particularly suitable for cost-sensitive and power-sensitive applications.

The S3F380D 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 S3F380D has been fully verified in the Samsung ASIC test environment.

By providing a complete set of common system peripherals, the S3F380D minimizes overall system costs and eliminates the need to configure additional components.

The integrated on-chip functions that are described in S3F380D 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
