C33 Macros

4.1 Special Operations

This chapter describes certain special operations that arise when developing ASICs that include C33

macros in the S1X50000 Series. Refer to the S1L50000 SERIES DESIGN GUIDE for information not

4.2 Verifying the C33 Macro Specifications

In the verification stage for ASICs that include C33 macros, the customer must verify the following

items in advance. Seiko Epson releases the C33 macro library based on these specifications.

1) C33 macro module selection

Refer to section 2.1, "Overview," and inform us of which modules will be used, whether or not

internal RAM/ROM is used, and other items.

2) C33 option pad selection

Refer to section 2.3, "C33 Macro Pins," and inform us which, if any, of the C33 optional pins

are not required.

3) C33 user pin selection

Refer to section 2.3, "C33 Macro Pins," and inform us which, if any, C33 optional pads must

be provided as C33 pins (internal signals) with the same function.

4) C33 macro pin I/O cell type selection

Refer to section 2.3, "C33 Macro Pins," and the "S1L50000 SERIES MSI Cell Library"

document, and inform us of the C33 macro pin I/O cell types.
