AK1594
Bluetooth® Low Energy transmitter
General
The AK1594 is a low power consumption transmitter IC that supports Bluetooth® 4.2. The AK1594 is a
simplest Bluetooth® Low Energy transmitter without the need for a microcontroller, providing advertising
data in the on-chip EEPROM.
Features
Single Chip Bluetooth® Low Energy Transmitter
Only the AK1594 and a few passive components are required to complete Bluetooth® Low
Energy advertising transmission function.
Microcontroller-less(MCU-less)
Bluetooth® Low Energy advertising transmissions can be broadcasted using the AK1594’s
on-chip EEPROM data. This MCU-less architecture eases system design without a
complicated development environment.
Functional Switches
4-hardware switches works as on-off, interval and power controller for advertising transmission.
Programmable Output Power
Support wide range output power from -32dBm to +6dBm.
Data whitening and CRC
Build–in data whitening feature and CRC that are compliant with Bluetooth® Low Energy.
Support GFSK(1Mbps)
Security
AES-128 Hardware Encryption
Package
28-pin QFN (4.0mm x 4.0mm x 0.70mm, 0.4mm pitch)

10. Function Description
10.1. TX MODE
There are two transmission modes “Continuous Burst Mode” and “Configured TX Mode”.
Continuous Burst Mode: {MODE} = “0b0”
The AK1594 continues RF transmission until the AK1594 detects SW2 pin falling edge.
SW2 pin falling edge valid only AUTO pin = "L" and {SW2_DIS} = "0b0".
Configured TX Mode: {MODE} = “0b1”
The AK1594 automatically stops transmission and goes to power down status after configured number
of transmission is attempted. The AK1594 can configure 1 to 5 transmissions that is set by {EVENTNUM
[2:0]}
The AK1594 automatically stops transmission triggered on SW1 falling edge. After the AK1594 detects
SW1 pin falling edge, the AK1594 does advertising transmission configured number of time (Note), and
then goes into power down status.
Note: The AK1594 can configure 1 to 5 transmissions that is set by {EVENTNUM [2:0]}

10.2. POWER MODE
There are two mode based on output power, Normal Power Mode and High Power Mode by setting
{POWR_MODE[1:0]}. Normal Power Mode has a benefit to save power. High Power Mode supports
+6dBm (Typ.) output.
10.3. Auto Operation mode
When AUTO pin set to “High”, the AK1594 starts burst transmission automatically after the AK1594
powered-on. {MODE} register is “0b0” automatically when AUTO pin = “H”. {SW2_DIS} value is “0b1”
automatically when AUTO pin = “H”.
AK1594 EEPROM cannot access when AUTO pin = “H”. AK1594 EEPROM access valid AUTO pin = “L”
and “Full power down” state.

10.4. Switch Action
10.4.1. SW1 pin
The AK1594 starts burst transmission triggered on SW1 pin input falling edges.
10.4.2. SW2 pin
The AK1594 sets to full power down state triggered on SW2 pin input falling edges during burst
transmission.
{SW2_DIS} enables or disables this function. This function is ignored when AUTO pin = “H”.
10.4.3. SW1 and SW2 Simultaneous Control(Reset)
When SW1 pin and SW2 pin are status “low” simultaneously more than 2 seconds, the AK1594 resets
internal digital blocks.
10.4.4. SW3 pin
SW3 provides two functions, Power Step Adjustment and High Power Switch.
-
Power step adjustment ({SW3_FUNC} = “0b0”)
TX power is changed every SW3 pin input triggered on falling edges. The AK1594 supports 6-state
power transition (SW3State) and power step size is defined by {SW3STEP[2:0]}. The AK1594 LED
function helps to determine which power state is configured monitoring number of LED blinks. When the
AK1594 doesn’t detect another SW3 falling edge for more than 4 seconds after the SW3 falling edge
detection, the AK1594 finishes internal process and begins burst transmission with the latest power state
setting.
-
High power switch({SW3_FUNC} = “0b1”)
The AK1594 switches transmission power to maximum by SW3 pin input. The maximum power is
programmed by register ({POWR_MODE [1:0]} =”0b11”, {POWRD [4:0]} =”31”). After maximum power is
set by this function, the AK1594 transmission power will not go down from maximum power setting
unless powered off (POR) or SW1 and SW2 simultaneous control.

10.4.5. SW4 pin
Advertising interval is changed every SW4 pin input triggered on falling edges. The AK1594 supports
6-state advertising interval (SW4State) and advertising interval length is defined by {SW4STEP[2:0]}.
The AK1594 LED function helps to determine which advertising interval length is configured monitoring
number of LED blinks. When the AK1594 doesn’t detect another SW4 falling edge for more than 4
seconds after the SW4 falling edge detection, the AK1594 finishes internal process and begins burst
transmission with the latest advertising interval length setting.

10.7. Battery monitor
The battery monitor controls LED and can set the AK1594 in power down.
LED Control
The battery monitor controls LED light ON or blinks when AVDD voltage drops below Detect Voltage1
(VALERT).
Power down controller
The battery monitor sets the AK1594 in full power down status when AVDD voltage drops below Detect
Voltage 2N or Detect Voltage2H. (VSLEEPN or VSLEEPH)
This function is controlled by {BAT_EN}. Detect voltage1 is not available when {POWR_MODE} = “0b10”,
or “0b11”.
Refer to 7.3 Characteristics of Battery monitor.
10.8. LED
The AK1594 has handy LED functions to know device status. LED pin drives 1mA or 3mA setting by
{I_LED}. To disable LED function for saving power consumption, LED pin should be set to open or

{SW3STEP[2:0]} are enabled by {SW3_FUNC} = “0b0”
When {SW3_FUNC} = “0b0”, the AK1594 changes output power at the SW3 pin falling edge. TX power
is set by {POWRD [4:0]})
When SW3 pin set to High to Low, AK1594 changes status from burst transmission to TX power setting
mode. The AK1594 changes TX power every SW3 pin falling edge during the TX power setting mode.
The AK1594 changes status SW3state1 → SW3state2 → SW3state3 → SW3state4 → SW3state5 →
SW3state6 → SW3state1 → SW3state2→, number of LED blinks shows status when
{SW3LED_EN}=”0b1”. LED blinking cycle is 360 msec.
When the AK1594 doesn’t detect another SW3 pin falling edge for more than 4 seconds after the SW3
pin falling edge detection, the AK1594 finishes this power step adjustment process and returns to burst
transmission.

The AK1594 changes advertising interval at the SW4 pin falling edge. Advertising intervals are set by
{ADVINTVL [14:0]}
When SW4 pin set to High to Low, AK1594 changes status from burst transmission to advertising
interval setting mode. The AK1594 changes interval timing every SW4 pin falling edge during the
advertising interval setting mode.
The AK1594 changes status SW4state1 → SW4state2 → SW4state3 → SW4state4 → SW4state5 →
SW4state6 → SW4state1 → SW4state2 →, number of LED blinks shows status when
{SW4LED_EN}=”0b1”. LED blinking cycle is 360 msec.
When the AK1594 doesn’t detect another SW4 falling edge for more than 4 seconds after the SW4
falling edge detection, the AK1594 finishes this advertising interval step adjustment process and returns
to burst transmission.
