APPENDIX C:

MIGRATION FROM

dsPIC30F601x TO

dsPIC30F601xA

DEVICES

The

dsPIC30F601xA

devices

supercede

the

dsPIC30F601x devices. The “A” version of the silicon is

identical in nearly all aspects compared to the

dsPID30F601x

devices.

Review

the

latest

dsPIC30F601x Silicon Errata documents posted on the

Microchip web to see what is fixed in the “A” version of

the silicon. This appendix describes the differences

between the dsPIC30F6011, 6012, 6013 and 6014 and

the dsPIC30F6011A, 6012A, 6013A and 6014A

devices, respectively.

C.1

PGC and PGD Programming Pins

The Programming Clock (PGC) and Data (PGD) pins

for the dsPIC30F6011A and dsPIC30F6012A devices

have been moved relative to the dsPIC30F6011 and

dsPIC30F6012 devices, respectively. The PGC/EMUC

function is now provided on the AN6/OCFA/RB6 pin

and the PGD/EMUD function is now provided on the

AN7/RB7

for

the

dsPIC30F6011A

and

dsPIC30F6012A devices. Programming of these two

devices must use the new PGC/EMUC and PGD/

EMUD pins.

The PGC/EMUC and PGD/EMUD pins on the

dsPIC30F6013A and dsPIC30F6014A devices have

not been changed relative to the dsPIC30F6013 and

dsPIC30F6014 devices, respectively.

C.2

Code Compatibility

For the most part, dsPIC30F code developed with the

MPLAB C30 C Compiler and MPLAB ASM30 Assem-

bler is directly portable between the dsPIC30F601x

and dsPIC30F601xA devices. However, in some cases

small changes may be required depending on which

features have been enhanced. To migrate source code

to the “A” version of the devices, perform these two

steps:

Include the appropriate dsPIC30F601xA device

header (.h), linker (.gld) and include (.inc)

files in the source code files.

Remove any workarounds implemented in

source code or MPLAB C30 Compiler com-

mand-line options for errata described in the

“dsPIC30F6011/6012/6013/6014 Rev. B2

Silicon Errata” (DS80198B) document.

Other changes are called out in this section. Read the

latest

dsPIC30F601xA

Silicon

Errata

documents

posted on the Microchip web site.

C.3

Oscillator Operation

Several oscillator modes have been added to the

dsPIC30F601xA devices:

• FRC with x4, x8 and x16 PLL mode

• HS/2 with x4, x8 and x16 PLL mode

• HS/3 with x4, x8 and x16 PLL mode

The

new

oscillator

modes

are

presented

Section 20.0 “System Integration”.

In support of the FRC, the OSCTUN Special Function

four FRC tuning bits (TUN<4:1>). This is a new feature

and hence there are no code or operational compatibil-

ity issues to address.

Another important change deals with the OSCCON

SFR. Bits have been added to both the COSC and

NOSC functional definitions. Use the “A” device header

(.h), linker (.gld) and include (.inc) files to achieve

code portability with the OSCCON SFR.

C.4

Device Configuration Registers

In support of the new Oscillator modes, the FOSC Con-

figuration

has

been

modified.

The

dsPIC30F6011A/6012A/6013A/6014A device header

and include files provide the updated bit field definitions

and macros for the device Configuration Registers.

Please refer to these new macros when embedding

specific device configuration information in the C and

Assembly source files.

C.5

Electrical Characteristics

The dsPIC30F6011A/6012A/6013A/6014A devices are

rated at 30MIPs @ 4.5-5.5 VDC and 20 MIPs @

3.0-3.6 VDC for the Industrial Temperature range.

Even though compatible devices are tested to the

same electrical specifications, the device characteris-

tics may have changed due to normal process varia-

tions. These differences should not affect the systems

that were designed well within the device specifica-

tions. For systems that operate close to or outside the

specification limits, manufacturing differences may

cause the device to behave differently.

Note:

Oscillator operation should be verified to

ensure that it starts and performs as

expected. You may need to adjust the load

capacitor and/or the Oscillator mode to

achieve the proper values.
