The P87CL881 is manufactured in an advanced CMOS technology and is based on single-chip technology. The device is optimized for low power consumption and has two software selectable features for power reduction: Idle and Power-down modes. In addition, all derivative blocks switch off their clock if they are inactive. The instruction set of the P87CL881 is based on that of the 8051. The P87CL881 also functions as an arithmetic processor having facilities for both binary and BCD arithmetic plus bit-handling capabilities. The instruction set consists of over 100 instructions: 49 one-byte, 46 two-byte, and 16 three-byte. This data sheet details the specific properties of the P87CL881; for details of the P87CL881 core and the derivative functions see the “TELX family” data sheet and “8051-Based 8-bit Microcontrollers; Data Handbook IC20”.
