S3P7235

S3C7238/P7238/C7235/P7235 PRODUCT OVERVIEW 1 OVERVIEW PRODUCT OVERVIEW The S3C7238/C7235 single-chip CMOS microcontroller has been designed for high performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers). With features such as LCD direct drive capability, 8-bit timer/counter, and serial I/O, the S3C7238/C7235 offer an excellent design solution for a wide variety of applications that require LCD functions. Up to 40 pins of the 80-pin QFP package can be dedicated to I/O. Six vectored interrupts provide fast response to internal and external events. In addition, the S3C7238/C7235's advanced CMOS technology provides for low power consumption and a wide operating voltage range. OTP The S3C7238/C7235 microcontroller is also available in OTP (One Time Programmable) version, S3P7238/P7235. S3P7238/P7235 microcontroller has an on-chip 8/16-Kbyte one-time-programmable EPROM instead of masked ROM. The S3P7238/P7235 is comparable to S3C7238/C7235, both in function and in pin configuration. 1-1 PRODUCT OVERVIEW S3C7238/P7238/C7235/P7235 FEATURES Memory – – – 512 × 4-bit RAM 8 K × 8-bit ROM (S3C7238/P7238) 16 K × 8-bit ROM (S3C7235/P7235) Bit Sequential Carrier – Support 16-bit serial data transfer in arbitrary format Interrupts – – – Three internal vectored interrupts Three external vectored interrupts Two quasi-interrupts I/O Pins – – – Input only: 8 pins I/O: 24 pins Output: 8 pins sharing with segment driver outputs Memory-Mapped I/O...
