Table 1 and Table 2 describe the signals for connector P1/RF1 and P2/RF2, respectively.
Table 1. Connector P1/RF1
Pin
Signal Name Description
No.
1 GND Ground
2 N/C No connection
3 MOD Direct mode, external modulation input
4 N/C No connection
5 N/C No connection
6 N/C No connection
7 IRQ Interrupt request (from TRF7960 to MCU)
8 N/C No connection
Clock for microcontroller (3.39 / 6.78 / 13.56 MHz) at EN = 1 and EN2 = don't care
9 SYS_CLK
If EN = 0 and EN2 = 1, then system clock is set to 60 kHz
10 EN Chip enable input (If EN = 0, then chip is in power-down mode).
11 N/C No connection
Pulse enable and selection of power down mode. If EN2 is connected to VIN, then VDD_X is active
12 EN2 during power down to support the microcontroller. Pin can also be used for pulse wake-up from
power-down mode.
13 N/C No connection
14 SLAVE SELECT Slave select, I/O 4 (active low)
15 N/C No connection
16 DATA_CLK Data clock input for microcontroller communication (from microcontroller)
17 N/C No connection
18 MOSI I/O 7, master out/slave in (data in from microcontroller)
19 GND Ground
20 MISO I/O 6, master in/slave out (data out from TRF7960)
