PRODUCT OVERVIEW
SAM8 PRODUCT FAMILY
Samsung's SAM87 family of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU, a wide
range of integrated peripherals, and various mask-programmable ROM sizes. Important CPU features include:
— Efficient register-oriented architecture
— Selectable CPU clock sources
— Idle and Stop power-down mode release by interrupt
— Built-in basic timer with watchdog function
A sophisticated interrupt structure recognizes up to eight interrupt levels. Each level can have one or more
interrupt sources and vectors. Fast interrupt processing (within a minimum of six CPU clocks) can be assigned to
specific interrupt levels.
KS88C0716/P0716 MICROCONTROLLERS
KS88C0716/P0716 single-chip 8-bit microcontrollers are based on the powerful SAM87 CPU architecture. The
internal register file is logically expanded to increase the on-chip register space. The KS88C0716 has 16-Kbyte
mask-programmable ROM. The KS88P0716 has 16-Kbyte one-time-programmable EPROM.
Following Samsung's modular design approach, the following peripherals are integrated with the SAM87 core:
— Seven programmable I/O ports (total 56 pins)
— One 8-bit basic timer for oscillation stabilization and watchdog functions
— One synchronous operating mode and three full-duplex asynchronous UART modes
— Two 8-bit timers with interval timer and PWM modes
— Two 16-bit general-purpose timer/counters
OTP
The KS88C0716 microcontroller is also available in OTP (One Time Programmable) version, KS88P0716.
KS88P0716 microcontroller has an on-chip 16-Kbyte one-time-programmable EPROM instead of masked ROM.
The KS88P0716 is comparable to KS88C0716, both in function and in pin configuration.
