Copro, PMMU & Masks

A little story

From 1994 to 1996, the 060 (at 50, 60 & 66 MHz) are produced with 3 versions and manufactured with 0.60um process :

- XC68060RCxx that contains a PMMU and a FPU (Floating Point Unit = Coprocessor).

- XC68LC060RCxx that contains a PMMU but NO FPU.

- XC68EC060RCxx that contains NO PMMU and NO FPU.

These first 060 are manufactured with the 1F43G mask (Rev.1) and accept up to 66 MHz (70% of them).

This mask has several bugs that get no problems on the CT60.

The RC letters define the type of package = PGA (Pin Grid Array) !

 

In 1996, the 1G65V mask appears for the three 060 models without one important bug on copro (F6). 

Later,

- the EC & LC change to 2G65V with NO bugs at all.

- the 'full' becomes 0E41J mask with NO bugs at all too.

See : 060_mask40.pdf

 

In 1998, the new 0.42um manufacturing process is used :

The EC & LC prefix change from XC to MC (final qualification) and their mask change from 2G59Y to 3G59Y : 

The 'full' change from 0E41J mask to 1E41J but stays with XC prefix.

See : 42um_status.html

 

In 1999, the XC68060RCxx is qualified and the prefix changes to MC with the new 71E41J mask :

See : mc_status.html

This last mask (Rev.6) is manufactured with 0.32um process and has the particularity to be able to run up to 100 MHz !

 

From 1999, the 75 MHz, manufactured with 0.32um process, arrives with 2 versions :

- MC68LC060RC75 that contains a PMMU and NO FPU.

- MC68EC060RC75 that contains NO PMMU and NO FPU.

A FPU story

The 060 needs a library to run the software using a FPU (using Fxxx instructions) !

In fact, only 1/3 of the 68882 (68030 FPU) instruction set - the most important/used instructions - was implemented in the 060 (and the 040 firstly), the remaining 2/3 must be emulated with this library that, sure, is integrated into the FLASH of the CT60.

The old 68882 FPU CAN'T run with a 060 ! But, sure, it can be used with the 030 when the CT60 is fitted and OFF !

 

The following lists were constructed by several persons I want to thank ! If you can update these lists, please contact me !

This list is not total (..) It is only here to answer the most general questions. See the software tested list on the main page !
