This item is subject to a minimum order quantity (MOQ), and the price per device will be lower for higher quantities. The prices for some representative quantities are shown below. If you want to order a different quantity, enter it below and add it to your cart to see the total cost (you can always delete items from your cart later).
PACKAGING. Please note that you will not necessarily receive your goods in standard packaging, even if you have ordered a quantity equal to, or more than a standard tube quantity. We may break down standard tube lengths into smaller lengths for more efficient shipment.
Devices in surface-mounted packages may be sensitive to absorbed moisture. Such devices supplied in smaller quantities without the manufacturers original moisture-controlled bulk packaging, should be 'baked out' according to the manufacturers recommendations before being subjected to reflow soldering processes. Such devices can however generally be manually soldered without special precautions.

The P89C660/662/664/668 device contains a non-volatile 16KB/32KB/64KB Flash program memory that is both parallel programmable and serial In-System and In-Application Programmable. In-System Programming (ISP) allows the user to download new code while the microcontroller sits in the application. In-Application Programming (IAP) means that the microcontroller fetches new program code and reprograms itself while in the system. This allows for remote programming over a modem link. A default serial loader (boot loader) program in ROM allows serial In-System Programming of the Flash memory via the UART without the need for a loader in the Flash code. For In-Application Programming, the user program erases and reprograms the Flash memory by use of standard routines contained in ROM.
This device executes one instruction in 6 clock cycles, hence providing twice the speed of a conventional 80C51. An OTP configuration bit gives the user the option to select conventional 12-clock timing.
This device is a Single-Chip 8-Bit Microcontroller manufactured in advanced CMOS process and is a derivative of the 80C51 microcontroller family. The instruction set is 100 pct executing and timing compatible with the 80C51 instruction set.
The device also has four 8-bit I/O ports, three 16-bit timer/event counters, a multi-source, four-priority-level, nested interrupt structure, an enhanced UART and on-chip oscillator and timing circuits.
The added features of the P89C660/662/664/668 makes it a powerful microcontroller for applications that require pulse width modulation, high-speed I/O and up/down counting capabilities such as motor control.
