DescriptionThe P80CL410; P83CL410 (hereafter generally referred to as the P8xCL410) is manufactured in an advanced CMOS technology that allows the device to operate at voltages down to 1.8 V and at frequencies down to DC. The P8xCL410 has the same instruction set as the 80C51.
The P8xCL410 features 4 kbyte ROM (83CL410), 128 bytes RAM (both ROM and RAM are externally expandable to 64 kbytes), four 8-bit ports, two 16-bit timer/counter, an I2C serial interface, a thirteen source two priority level nested interrupt structure, and on-chip oscillator circuitry suitable for quartz crystal, ceramic resonator, RC, or LC. The device operates over a wide range of supply voltages and has low power consumption.
The 8xCL410 has two reduced power modes that are the same as those on the standard 80C51.
The special reduced power feature of P83CL410 is that it can be stopped and then restarted. Running from an external clock source, the clock can be stopped and after a period of time restarted. The 8xCL410 will resume operation from where P83CL410 was when the code stopped with no loss of internal state, RAM contents, or Special Function Register contents.
If the internal oscillator is used the P83CL410 cannot be stopped and started, but the Power-down mode can be used to achieve similar power savings, without loss of on-chip RAM and Special Function Register values. The Power-down mode can be terminated via an interrupt.
This data sheet details the specific properties of the P80CL410; P83CL410. For details of the 80C51 core see "Data Handbook IC20".
For emulation purposes, the P85CL000 (piggy-back version) with 256 bytes of RAM is recommended. Details are given in Chapter 22.
