Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_22632 ( "Model number" text, "sSpec number" text, "Frequency" text, "Turbo" text, "Cores" real, "L2 cache" text, "L3 cache" text, "I/O bus" text, "Mult." text, "Memory" text, "Voltage" text, "TDP" text, "Socket" text, "Release date" text, "Part number(s)" text, "Release price ( USD )" text )

### Question ###
When by80607002529af is the part number and september 2009 is the release date what is the l2 cache?

### Accurate SQL ###

SELECT "L2 cache" FROM table_22632 WHERE "Release date" = 'September 2009' AND "Part number(s)" = 'BY80607002529AF'
