... RAMs and are identical except that in -40 to +85 E20.3 the CDP1882 MWR and MRD are excluded. -40 to +85 E18.3 The CDP1882 is functionally identical to the CDP1882C. It differs in that the CDP1882 has recommended operating -40 to +85 E18.3 voltage range 10.5V and the C version has a recom- mended operating voltage range 6.5V. ...
