X=0,3 or 7.L-low voltage version.Operates at 3 volts.
*20MHz for commercial and 16MHz for express:
In table 6.1 from (6) to (11) the microcontrollers with X = 0 are ROMless;with X = 3,are with ROM; and with X=7,are EPROM/OTP.FROM 1 to 5,products with X = 0 and X = 7 are available.With X = 7,products are with EPROM/OTP,With X = 0,the products 80C51BH,80C52,80C54,80C58,80L52,80L54 and 80L58 are with ROM.The products 80C31BH and 80C32 are ROMless.

X = 0,3或7 . L型低电压版本.工作在3伏特.
*为20MHz和16MHz商业的表达：
从表6.1中（ 6 ） （ 11 ）的微控制器与X = ○顷ROMless ;与X = 3 ,是与光盘;和与X = 7 ,是可擦写可编程只读存储器/检察官办公室.从1到5 ,产品与X = 0和X = 7可用.与X = 7 ,产品与可擦写可编程只读存储器/检察官办公室,与X = 0 ,产品80C51BH , 80C52 , 80C54 , 80C58 , 80L52 , 80L54和80L58是与光盘.产品80C31BH和80C32是ROMless .
