The majority of the proposed detector concepts for the ILC are built around the particle flow algorithm (PFA) approach which requires a highly granular calorimeter. The leading proposed technology for a PFA electromagnetic calorimeter at the ILC is using silicon-tungsten. We have developed a monolithic active pixel sensor for silicon-tungsten calorimeters, which would have extremely fine granularity, allowing binary pixel readout and the usage of digital electromagnetic calorimetry. A first generation chip (TPAC 1.0) has been fabricated, which contains a 168×168 pixel array, consisting of 50×50μm2 pixels with integrated charge pre-amplifier and comparator. TPAC 1.0 has been manufactured in the 180 nm CMOS INMAPS process which includes a deep p-well implant. We present recent results of the performance of the TPAC 1.0 chip and give an outlook on its successor TPAC 1.1.
