KS57P21832 Datasheet | Samsung Semiconductor

OVERVIEW OVERVIEW PRODUCT OVERVIEW The KS57C21832 single-chip CMOS microcontroller has been designed for high performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers). With an up-to-896-dot LCD direct drive capability, 8-bit timer/counter 0, 16-bit timer/counter 1, and serial I/O, the KS57C21832 offers an excellent design solution for a wide variety of applications which require LCD functions. Up to 39 pins of the 100-pin QFP package can be dedicated to I/O. Eight vectored interrupts provide fast response to internal and external events. In addition, the KS57C21832's advanced CMOS technology provides for low power consumption and a wide operating voltage range. The KS57C21832 microcontroller is also available in OTP (One Time Programmable) version, KS57P21832. KS57P21832 microcontroller has an on-chip 32 K-byte one-time-programable EPROM instead of masked ROM. The KS57P21832 is parable to KS57C21832, both in function and in pin configuration. 1-1 PRODUCT OVERVIEW KS57C21832/P21832 FEATURES SUMMARY Memory - - 8,192 × 4-bit RAM (excluding LCD display RAM) 32,768 × 8-bit ROM - 39 I/O Pins - - I/O: 35 pins Input only: 4 pins Interrupts - LCD Controller/Driver - - - - 56 segments and 16 mon terminals 8 and 16 mon selectable Internal resistor circuit for LCD bias All dot can be switched on/off Bit Sequential Carrier - Supports 16-bit serial data transfer in arbitrary format - - Four internal vectored interrupts Four external vectored interrupts Two quasi-interrupts - Watch Timer - Time interval generation: 0.5 s, 3.9 ms at 32768 Hz 4 frequency outputs to BUZ pin Clock source generation for LCD 8-bit Basic Timer - - 4 interval timer functions Watchdog timer Power-Down Modes - - - Idle mode (only CPU clock stops) Stop mode (main system clock and CPU clock stop) Sub-system clock stop mode 8-bit Timer/Counter 0 - - - - - Programmable 8-bit timer External event counter Arbitrary clock frequency output External clock...
