STMicroelectronics 

STLC2500

1 FEATURES

■ Bluetooth™ specification compliance: V1.1 and

V1.2

■ Ericsson Licensing Technology Baseband Core

(EBC)

■ Point-to-point, point-to-multi-point (up to 7

slaves) and scatternet capability

■ Asynchronous Connection Oriented (ACL)

logical transport link

■ Synchronous Connection Oriented (SCO) link:

2 simultaneous SCO channels

■ Support Pitch-Period Error Concealment (PPEC)

– Improves speech quality in the vicinity of in-

terference

– Improves coexistence with WLAN

– Works at receiver, no Bluetooth implication

■ Adaptive Frequency Hopping (AFH): hopping

kernel, channel assessment as Master and as

Slave

■ Faster Connection: Interlaced scan for Page

and Inquiry scan, first FHS without random back

off, RSSI used to limit range

■ Extended SCO (eSCO) links

■ HW support for packet types

– ACL: DM1, 3, 5 and DH1, 3, 5

– SCO: HV1, 3 and DV

– eSCO: EV3, 5

■ Clock support

– System clock input (digital or sine wave) at

13, 26, 19.2 or 38.4 MHz

– LPO clock input at 3.2, 16.384, 32 or 32.768 kHz

■ ARM7TDMI CPU

– 32-bit Core

– AMBA (AHB-APB) bus configuration

■ Patch RAM capability

■ Memory organization

– On chip RAM, including provision for patches

– On chip ROM, preloaded with SW up to HCI

■ Communication interfaces

– Fast UART

– PCM interface

– 4 programmable GPIOs

– External interrupts possible through the GPIOs

– Fast master I2C interface

■ Efficient support for WLAN coexistence in

collocated scenario

■ Ciphering support up to 128 bits key

■ Software support

– Lower level stack (up to HCI)

– HCI Transport Layer: H4 (including propri-

etary extensions)

– HCI proprietary commands (e.g. peripherals

control)

– Single HCI command for patch/upgrade download

■ Single power supply with internal regulators for

core voltage generation

■ Supports 1.65 to 2.85 Volts IO systems

■ Total number of external components limited to 7

(6 decoupling capacitors and 1 filter) thanks to:

– Fully integrated synthesizer (VCO and loop filter)

– Integrated antenna switch

– Low IF receiver

■ Auto calibration (VCO, Filters)

■ No need for calibration of the RF part

■ Timer and watchdog

■ Power class 2 compatible

■ Ultra low power architecture with 3 different low

power levels:

– Sleep Mode

– Deep Sleep Mode

– Complete Power Down Mode

■ Software Initiated Low Power Mode

■ Dual Wake-up mechanism: initiated either by

the Host or by the Bluetooth device

■ Standard TFBGA-84 pins package

2 DESCRIPTION

The STLC2500 is a single chip ROM-based Blue-

tooth solution implemented in 0.13 m ultra low

power, low leakage CMOS technology for applica-

tions requiring integration up to HCI level. Patch

RAM is available enabling multiple patches/up-

grades.

The STLC2500's main interfaces are UART for

HCI transport, PCM for voice and GPIOs for con-

trol purposes. The Radio is designed for the single

chip requirement and for drastic power consump-

tion reduction.
