PIC24HJ32GP202/204 and

PIC24HJ16GP304

The PIC24HJ32GP202/204 and PIC24HJ16GP304

family devices that you have received conform

functionally to the current Device Data Sheet

(DS70289H), except for the anomalies described in this

document.

The silicon issues discussed in the following pages are

for silicon revisions with the Device and Revision IDs

listed in Table 1. The silicon issues are summarized in

Table 2.

The errata described in this document will be addressed

in future revisions of the PIC24HJ32GP202/204 and

PIC24HJ16GP304 silicon.

Data Sheet clarifications and corrections start on page

10, following the discussion of silicon issues.

The silicon revision level can be identified using the

current version of MPLAB

IDE and Microchip’s

programmers, debuggers and emulation tools, which

are available at the Microchip corporate web site

(www.microchip.com).

For example, to identify the silicon revision level using

MPLAB IDE in conjunction with MPLAB ICD 3 or

PICkit™ 3:

1. Using the appropriate interface, connect the device

to the MPLAB ICD 3 programmer/debugger or

PICkit 3.

2. From the main menu in MPLAB IDE, select

onfigure>Select Device, and then select the

target part number in the dialog box.

3. Select the MPLAB hardware tool

(Debugger

>Select Tool).

4. Perform a “Connect” operation to the device

(Debugger>Connect

). Depending on the

development tool used, the part number and

Device Revision ID value appear in the Output

window.

The Device and Revision ID values for the various

PIC24HJ32GP202/204 and PIC24HJ16GP304 silicon

revisions are shown in Table 1.

Note: This document summarizes all silicon

errata issues from all revisions of silicon,

previous as well as current. Only the

issues indicated in the last column of

Table 2 apply to the current silicon

revision (A6).

Note: If you are unable to extract the silicon

revision level, please contact your local

Microchip sales office for assistance.

PIC24HJ32GP202/204 and PIC24HJ16GP304 Silicon Errata Issues Note: 4. Module: UART This document summarizes all silicon errata issues from all revisions of silicon, previous as well as current. Only the issues indicated by the shaded column in the following tables apply to the current silicon revision (A6). The auto-baud feature may miscalculate for certain baud rate and clock speed combinations, resulting in a BRG value that is greater than or less than the expected value by 1.
PAGE 5
PIC24HJ32GP202/204 and PIC24HJ16GP304 10. Module: I2C 7. Module: UART When the UART is in 4x mode (BRGH = 1) and using two Stop bits (STSEL = 1), it may sample the first Stop bit instead of the second one. This issue does not affect the other UART configurations. Work around Use the 16x baud rate option (BRGH = 0) and adjust the baud rate accordingly.

PAGE 6
PIC24HJ32GP202/204 and PIC24HJ16GP304 16. Module: I2C 13. Module: UART When the UART is operating in 8-bit mode (PDSEL = 0x) and using the IrDA encoder/decoder (IREN = 1), the module incorrectly transmits a data payload of 80h as 00h. Work around When the I2C module is configured as a 10-bit slave with an address of 0x02, the I2CxRCV register content for the lower address byte is 0x01 rather than 0x02; however, the module acknowledges both address bytes. Work around None.

PIC24HJ32GP202/204 and PIC24HJ16GP304 19. Module: I2C When the I2C module is operating in either Master or Slave mode, after the ACKSTAT bit is set when receiving a NACK, it may be cleared by the reception of a Start or Stop bit. Work around Store the value of the ACKSTAT bit immediately after receiving a NACK. Affected Silicon Revisions A2 A3 A4 A5 A6 X X X X X 21.

PIC24HJ32GP202/204 and PIC24HJ16GP304 23. Module: ADC 24. Module: All If the ADC module is in an enabled state when the device enters Sleep mode as a result of executing a PWRSAV #0 instruction, the device power-down current (IPD) may exceed the specifications listed in the device data sheet. This may happen even if the ADC module is disabled by clearing the ADON bit prior to entering Sleep mode. The affected silicon revisions listed below are not warranted for operation at 150ºC.

PIC24HJ32GP202/204 and PIC24HJ16GP304 25. Module: CPU 27. Module: UART When a previous DISI instruction is active (i.e., the DISICNT register is non-zero), and the value of the DISICNT register is updated manually, the DISICNT register freezes and disables interrupts permanently. Work around Avoid updating the DISICNT register manually. Instead, use the DISI #n instruction with the required value for 'n'.
