Under the AMD logo is the product name. In the case of the AMD K6 series, the product name reads AMD-K6. Under the product name is the ordering part number. The ordering part number includes the operating frequency. A K6/233MHz will read 233. A K6/200MHz will read “200”, etc. Next to the operating frequency you will find a single letter that identifies the package type. Currently there is only one. This letter is A. The A means that the chip has a 321 pin Ceramic Pin Grid Array. Next to the package type you will find a single letter that identifies the operating voltage. The two values that for this are the following: • L – 2.755V to 3.045V Core and 3.135V – 3.6V I/O • N – 3.1V to 3.3V Core and 3.134V to 3.6V I/O • P – 3.3V core and 3.3V I/O The last letter on in the ordering part number is the ID for the maximum case temperature for the chip. An “R” means that the maximum case temperature is 70 degrees Celsius. Under the ordering part number is the core voltage. Valid values are 2.9V,
