80pcs Samsung S3C7515 SAM47 core 4bit microrontroller, individual silicon dies

You are purchasing a full tray of 80pcs Samsung S3C7515 SAM47 core 4bit microrontroller silicon dies. The plastic tray measure 5cm x 5cm, and each individual die measure 3.73mm x 3.44mm. These represent a great example of semiconductor manufacturing technology from 2004 and makes for great educational, collection and display item. The dies will produce shiny, multicolored rainbow reflection with light, like a CD. The dies are new old stock, never used, and will be packaged safely. Please look at the photos carefully.

The S3C7515/P7515 single-chip CMOS microcontroller has been designed for high-performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers). The S3P7515 is a microcontroller which has 16-kbyte one-time-programmable EPROM but its functions are same to S3C7515. With its DTMF generator, 8-bit serial I/O interface, and versatile 8-bit timer/counters, the S3C7515/P7515 offers an excellent design solution for a wide variety of telecommunication applications. Up to 55 pins of the 64-pin SDIP or QFP package can be dedicated to I/O. Seven vectored interrupts provide fast response to internal and external events. In addition, the S3C7515/P7515's advanced CMOS technology provides for low power consumption and a wide operating voltage range. All S3C7-series microcontrollers have the advanced SAM47 CPU core. The SAM47 CPU can directly address up to 32 K bytes of program memory. The arithmetic logic unit (ALU) performs 4-bit addition, subtraction, logical, and shift-and-rotate operations in one instruction cycle and most 8-bit arithmetic and logical operations in two cycles.
